<div style="text-align: justify;">
As power transistor handle large currents, they always heat up during operation. Since transistor is a temperature dependent device, the heat generated must be dissipated to the surrounding in order to keep the temperature within permissible limits. Generally, the transistor is fixed on a metal sheet (usually aluminum) so that additional heat is transferred to the Aluminum sheet. The metal sheet that serves to dissipate the additional heat from the power <a href="http://www.circuitstune.com/search/label/Transistor%20Circuit">transistor</a> is known as heat sink.</div>

<div style="text-align: justify;">
Most of the heat within the transistor is produced at the collector junction. The heat sink increases the surface area and allows heat to escape from the collector junction easily. The result is that temperature of the transistor is sufficiently lowered. Thus almost the entire heat in a transistor is produced at the collector-base junction. If the temperature exceeds the permissible limit, this junction is destroyed and the transistor is rendered useless. <br />
Most of power is dissipated at the collector-base junction. This is because collector-base voltage is much greater than the base-emitter voltage, although currents through the two junctions are almost the same.<br />
<br />
Heat sink is a direct practical means of combating the undesirable thermal effects e.g. thermal runaway. It may be noted that the ability of any heat sink to transfer heat to the surrounding depends upon its material, volume, area, shape, contact between case and sink and movement of air around the sink. Finned aluminum heat sinks yield the best heat transfer per unit cost. It should be realized that the use of heat sink alone may not be sufficient to prevent thermal runaway under all conditions. In <a href="http://www.circuitstune.com/2011/12/circuit-design-tutorial-in-circuitmaker.html">designing a transistor circuit</a>, consideration should also be given to the choice of (i) operating point (ii) ambient temperatures which are likely to be encountered and (iii) the type of transistor e.g. metal case transistors are more readily cooled by conduction than plastic ones. Circuits may also be designed to compensate automatically for temperature changes and thus stabilize the operation of the transistor components.</div>

Theory of operation of this automatic power off circuit</h3>
<ul style="text-align: left;">
<li>Here <b>IC 555</b> is used as <a href="http://www.electronics-tutorials.ws/waveforms/monostable.html" rel="nofollow" target="_blank">Monostable Multivibrator</a>. It is a popular and very widely used timer IC. </li>
<li>Input power for this timer circuit is provided using a transformer-less power supply which is made with a diode as a half wave rectifier, a voltage drop resistor, a filter capacitor and a zener diode.</li>
<li>In power supply section, diode D1 is used as a half wave rectifier </li>
<li>And R1 used as a voltage drop resistor and C1 used as filter capacitor</li>
<li>S1, a push button switch is used to trigger the timer IC</li>
<li>And the 555 timer output goes through a resistor (R4) to the ‘Gate’ of the TRIAC BT136</li>
<li>When timer output is high it triggers the TRIAC and turn on the load/output device</li>
<li>When C2 (time delay capacitor) charge up to 2/3 of input voltage; then 555 output goes low (Pin-3 is the output pin of 555)</li>
<li>As timer output goes low, the TRIAC turn off the load/output device</li>
<li>Here set time is around <span style="color: red;">20 minutes</span></li>
<li><b>Set time can be adjusted by changing the C2 value</b></li>
<li>A low leakage capacitor is recommended as C2</li>

<b>Circuit Description:</b></h3>
TX is a Center taped step down Transformer (230V,50Hz; 12-0-12,3A). For bridge rectifier use Diode 1N5408, 1N5407 etc. Use 10KΩ to 100KΩ as R3. VR 100K is a POT/Variable Resistor to control sound level. Capacitor C1,C2,C3,C4 is used as filter capacitor to reduce the ripple factor(AC element in DC). If ripple factor is high in supplied DC voltage of an amplifier, then output audio signal of that amplifier will be noisy. Remember that high ripple factor is responsible for high noise.<br />
The main attraction of an audio amplifier is its high output power and very low noise. For this requirement, this 10W audio amplifier circuit using this IC-TDA2030 is very good within low cost.<br />

<b>Note:</b></h4>
<ul>
<li>Use transformer with (12-0-12,3A) output voltage.</li>
<li>Don’t use higher than 2200Hz,25V capacitor as C3,C4. That may damage the IC.</li>
<li>Must use <a href="http://www.circuitstune.com/2012/11/heat-sink_20.html" target="_blank"><b>Heat Sink</b></a> with the IC-TDA2030. Without proper Heat Sink the IC will be in risk of fry up</li>
<li>Don’t use smaller than 1N54XX diode like 1N40XX, 1N40XX(ex:1N4001)
may get damaged. We recommend to use four <b>1N5408</b> for bridge rectifier. </li>
<li>All ground point in the circuit should be connected in a single
point and ground it(If possible) or connect in transformers ''0'' marked
wire as shown in the circuit.</li>

Circuit Description </h3>
<div style="text-align: left;">
A S9014 NPN transistor is used here; you can use BC547 as an alternative of it. All the capacitor used in circuit is <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEixLS1L0VklneVzS5DsGXLxpl-PSkvlZ5o-cY9LPFqxfN2R5-gl4Nmwvj7HcprRPyliFpRQ3v9PE6xePbgaI0o0m2BFfjlBLjQOo6Q9VQmPyVAoo76kRfuCKjwuxFEh3Ai9RSefYmIB7QM/s1600/Ceramic-Capacitors.jpg" target="_blank">ceramic capacitor</a>. Don’t be surprised with the supply voltage of 1.5 volt. Here you can use a single 1.5V AA battery cell, or a 3V battery that will be endurable for this this FM transmitter circuit. A small microphone used here is an electret condenser type microphone (see below). Must use at least a small antenna for a higher transmitting-range. Then try with a bigger antenna for increasing range. </div>

Circuit Description</h4>
<div style="text-align: left;">
As shown in the circuit a very few number of parts is used including relay, transformer, condenser microphone, few transistor, a lamp etc. Lamp is used as a testing device; here another device could be use like fan, <a href="http://www.circuitstune.com/2012/02/music-generator-circuit-using-um66-ic.html" target="_blank">calling bell</a>, radio etc. </div>
<div style="text-align: left;">
<br />
The basic principle applied in this circuit: </div>
<blockquote class="tr_bq">
<div style="text-align: left;">
<i>“Clap sound is being converted into electrical signal and a relay gets triggered from it and controls the load.”</i></div>
</blockquote>
<div style="text-align: left;">
<br />
A small microphone (MIC) detects the clap sound and converts into electrical signal. Which is amplified by Q1 (here Q1 used as a common emitter amplifier). Amplified signal goes into the Bistable Multivibrator section made by two transistors Q2 and Q3.</div>
<div style="text-align: left;">
<br />
When we apply a trigger to the Bistable Multivibrator circuit with a clap sound then, if Q2 is on, Q3 gets switched off. Thus, the circuit remains stable in a single state continuously. At the moment if we trigger with another clap sound the two states will flip-flop with Q2 switched off and Q3 switched on. The circuit will remain stable continuously until we apply the next trigger.</div>
<div style="text-align: left;">
<br />
Relay gets triggered from the output of current-amplifier (Q4) which is used to amplify the flip-flop signal. Relay is kind of electromagnetic switch, which is used to controlling other high voltage (AC) electrical appliance (Load in our circuit) with this low voltage (DC) clap switch.<br />

A tube-light get fused due to use from a long time. You may notice that a used fluorescent tube-light get black colored on the both end of it. This circuit is to light-up those fused tube-light.<br />Have you think about re using a fused tube light? (Which is usually thrown out). Well here I’m showing a simple circuit using 4 diode for re-using a fused tube light. <br />

The circuit diagram shown above is quite simplified from basic <a href="http://www.circuitstune.com/2012/01/fluorescent-light-wiring-diagram-tube-light-circuit.html" target="_blank">tube light wiring diagram</a> by adding a bridge rectifier. Bridge rectifier provides high voltage DC to the both end of tube. All we have focused in this project is to lighting-up the weak tube using high voltage DC.<br /><br /><b>Note:</b> A fully damaged or broken tube-light could not be light-up anyway. Use those tube-light for this project that is still trying to light-up but not fully lightened on the <a href="http://www.circuitstune.com/2012/01/fluorescent-light-wiring-diagram-tube-light-circuit.html" target="_blank">basic connection of tube-light.</a></div>

Here this is a simplest circuit for <b>100 watt inverter</b> for generating 220vAC from 12vDC. I say simplest because here in this inverter circuit a minimum number of components are used to design the schematic, which is quite difficult to make a circuit like this with further fewer components.<br />

This 100W inverter circuit works great for small loads like a fan or 2-3 bulbs/lamps. In this circuit as IC1 we used a CD 4047 IC to generate 100Hz frequency (180 degree out of phase). CD 4047 IC is from Texas Instruments. It is mostly used as Astable/Monostable signal generator device. In this circuit it is triggered as <a href="http://www.circuitstune.com/2012/01/astable-multivibrator-2-led-flashing.html" target="_blank">astable multivibrator</a> by the capacitor C1 between the Pin 1 and 3 of CD4047. And VR1 is used to adjust the frequency of signal.<br />
<a name='more'></a><br />
Four 2N3055 transistors are used to amplify the pulse trains that are pre-amplified by two TIP122 transistors. There used three transistors for each side (half cycle), one TIP122 & two 2N3055 transistor to drive the output transformer (TX in circuit). Four 2N3055 transistors are used as driving transistor. An inverters maximum output power depends on two factors; one is the max current rating of transformer’s primary winding and other factor is the current rating of driver transistors.<br />
<br />
<b>Transformer: </b>Use a 12v-0-12v, 10A step-down transformer in reverse. That’s mean secondary winding (12v-0-12v) will be the primary and primary winding (220VAC side) will be the secondary (output). So that it will worked like a step-up transformer. You can also use a 5A transformer instead of 10A, if you couldn’t have 10A. But the output power will decrease to 60 Watt.<br />
<br />
<b>+12VDC:</b> A good quality 12V car battery could be used for DC 12V.<br />

<div style="text-align: justify;">
This is a water sensor /rain alarm circuit diagram; it can be used on motorcycle, car or other device that we want to protect from water, rain. <br />
This is a simple water sensor/rain alarm circuit that makes an alarm when water/rain falls on its sensor. This circuit is based on NE555/LM555 IC and two transistors (Q1&Q2). For transistor Q1- BC547 or BC107 and for Q2- 2N825,BC548 or BC168 can be used in the circuit. This rain detector circuit can be supplied from voltage source of +9V-12V DC. The resistor 470K ohm is a POT/Variable resistor; it is used to adjust the sensitivity of water/rain sensor. Use a 8 ohm,0.5w-1W speaker to hearing better alarm. Less than 8 ohm speaker could be harmful for the IC 555.</div>

This is a simple illustrated <i><b>circuit diagram of ceiling fan</b></i>. To be noted that the wiring diagram is for AC 220V single phase line with single phase ceiling fan motor. Here a simple SPST switch is used to supply power or not to the fan motor and a Regulator is used to controlling the fan speed. Though it is very simple, but one thing to be noted that <b>Switch</b> and <b>Regulator</b> should be connected with the phase line of main power, not neutral.<br />

As it is a <i><b>capacitor start-capacitor run</b></i> type motor; there a capacitor is used in series with <b>Starting Winding</b>, It defines the direction of rotation. It is an electrolytic capacitor.<br />
<br />
<h4>
Sometimes you may have faced this type of question...</h4>
<div style="text-align: left;">
</div>
<ol style="text-align: left;">
<li>Why ceiling fan rotating in reverse?</li>
<li>What makes a ceiling fan run backwards?</li>
</ol>
<div style="text-align: left;">
Two of this question sounds the same; the answer of the both question is “If capacitor is connected with <b>running winding/main coil</b> instead of <b>starting winding/auxiliary coil</b> then the direction of rotation will changed. That’s mean if you want <b>to change the direction of rotation of the fan, just connect the capacitor with other winding.</b></div>

<div style="text-align: justify;">
A <b>voltage regulator</b> is used to produce a constant linear output voltage. It’s generally used with AC to DC power supply. And also it can be used as well as a <a href="http://www.circuitstune.com/2011/12/12-to-5-volt-dc-dc-converter-circuit.html" target="_blank">DC to DC voltage converter</a> . To regulating low voltage, most used device is one single IC. 7805, 7812, 7905 etc. 78xx series are design for positive and 79xx series are for Negative voltage regulator. </div>
<br />
<div style="text-align: justify;">
<b>7805</b> is a three terminal +5v voltage regulator IC from 78XX chips family. See <i><b>7805 pinout</b></i> below. LM78XX series are from National Semiconductor. They are linear positive voltage regulator IC; used to produce a fixed linear stable output voltage. National Semiconductor has also negative voltage regulator chips family, they indicate with LM 79XX. 78xx is used more than 79xx because negative voltage has a few usability purposes as we see.<br />
I was previously posted a <a href="http://www.circuitstune.com/2011/11/5v-regulated-power-supply-circuit.html" target="_blank">5v regulated power supply circuit using 7805 IC</a>, that circuit and this <i><b>7805 voltage regulator circuit</b></i> is almost the same.</div>

Its output voltage is +5V DC that we need. You can supply any voltage in input; the output voltage will be always regulated +5V. But my recommendation is, don’t supply more than 18V or less than 8V in input. There used two capacitors in this voltage regulator circuit, they aren’t mandatory to use. But it will be best if you use them. They helped to produce a smooth regulated voltage at output. Use electrolyte capacitor instead of ceramic capacitor. </div>
<div style="text-align: justify;">
<br />
One limitation of <b>7805</b> I have found that is its output current <b>1A</b> maximum. Otherwise it is a good <b>voltage regulator</b> if you are happy with 1A. But if you need <b>over 400mA</b> current in output then you should use a <a href="http://www.circuitstune.com/2012/11/heat-sink_20.html" target="_blank"><b>Heat Sink</b></a> with IC LM7805. Otherwise it may fall damage for overheating. </div>

<span style="font-size: small;"><b>How Fluorescent Light's works:</b></span></h4>
</div>
<div class="MsoNormal" style="font-family: Verdana,sans-serif; text-align: justify;">
<span style="font-size: small;">The starter is like a key of fluorescent light because it is used to light up the tube. When we connect the AC supply voltage to the circuit, then the starter act like short circuited and current flow through those filament (located at the first and second end of the tube light) and the filament generate heat and it ionized the gas (<span class="st">mercury </span><i><span style="font-style: normal;">vapor</span></i>) in the fluorescent tube lamp. So the gas becomes electrically conductive medium. At the same time when the starter opened the circuit path of two filaments from series connected, then the ballast release its stored voltage. And it makes the fluorescent tube fully lighten. Now the starter has no job in the circuit, if you open it from the circuit the fluorescent tube light will be still lighten, until you release the main supply.</span></div>

When the LDR (Light Depended Resistor) is in light its resistance is low, and when in dark its resistance goes higher. When the light level decreases means the LDR is in darks then LDR goes its maximum threshold resistance, then the circuit automatically switches on the LED. Here I used a 1K variable resistor as R3 to adjust the dark/light sensitivity of the circuit.</div>

<b>LA4440 Bridge Amplifier Circuit</b></h3>
</div>
<div style="text-align: justify;">
When the IC LA4440 is in Bridge mode in the circuit, its output power is 19w. In bridge mode use 4Ω-8Ω speaker. If you want stereo output(19w+19w) in bridge mode then use two copies of amplifier circuit of given below. Resistor R3&R4 is to adjust the voltage gain and for making input signal of inverting amplifier.</div>

Circuit description for both, stereo and bridge amplifier mode</h3>
</div>
<div style="text-align: left;">
<br /></div>
<div style="text-align: justify;">
C10 is filter capacitor used to reduce the ripple of supply voltage. Don’t decrease the value of capacitor C6&C7 less than 100uF, 10v, it may causes of the output at low frequencies goes lower. The pin-6 of LA4440 amplifier circuit is audio input pin; it used in stereo amplifier mode but in bridge mode it is grounded. C8&C9 are polyester film capacitor used to preventing oscillation, and R1&R2 used for the same reason as filter resistor. Though the maximum supply voltage for both circuit of amplifier is 18V but we recommend to use a 12V,3A <a href="http://www.circuitstune.com/search/label/Power%20Supply" target="_blank">power supply</a>. Use a good quality <a href="http://www.circuitstune.com/2012/11/heat-sink_20.html" target="_blank"><b>heat sink</b></a> with LA4440. </div>
<div style="text-align: left;">
<br /></div>
<div style="text-align: justify;">
I think here you see little comparison between stereo and bridge amplifier of LA4440. If you want to make this amplifier project, then I recommend you the bridge one. I think it is ideal for a beginner. And I love its wattage rather than Stereo mode. There is also a possibilities as I say, make two copies of circuit of bridge amplifier for stereo, it will give you 19w+19w of audio power output.</div>

If you want to going with battery, no problem the amplifier can also operate by even 3V Battery cell . The IC TDA7052 no needed any <b><a href="http://www.circuitstune.com/2012/11/heat-sink_20.html" target="_blank">Heat Sink</a></b>. In the circuit R2 is a Variable Resistor, used as volume controller.

When mains is connect to the circuit, the Capacitor(C1) starts charging through Diode(D1) and Resistor(R1). When the voltage on the capacitor reached the DIAC’s threshold voltage, the DIAC get turn on. And LED gets Lights(flash). At the same time Capacitor(C1) goes discharges and breakover voltage of DIAC also decrease and LED turns OFF. The on off time of the LED depends on the value of Capacitor(C1) and Resistor(R1).<br />

This is a simple (song) music generator circuit using ic UM66. To make a musical calling-bell, door-bell, kids toys etc. we can use this funny audio/sound/music/tone generator ic UM66. The UM66 series are CMOS IC’s, they has a built in ROM to store the music. The IC operates in DC +3V. We suggest to use two dry cell (1.5V X 2) for +3V Supply. For Q1 use a TO-92 type NPN transistor like BC548, BC168, BC183, BC238, 2N2222. Speaker must be 4Ω or higher.</div>

We are all done and you can see in screenshot, the output voltage is 5V DC. And that is our expected output and circuit. If you want to know more about <a href="http://www.circuitstune.com/2011/12/12-to-5-volt-dc-dc-converter-circuit.html">12Vto 5V dc-dc converter circuit</a> then follow this <a href="http://www.circuitstune.com/2011/12/12-to-5-volt-dc-dc-converter-circuit.html">link.</a></div>

Thank you for reading. Have you faced any problem when trying to design the circuit and have I missed anything? </div>
<span style="font-family: "Trebuchet MS",sans-serif;"> </span><br />
<div class="MsoNormal" style="font-family: "Trebuchet MS",sans-serif; text-align: justify;">
What you think? Should i post more tutorial about circuit design and CircuitMaker 5.</div>
