The built in circuitries inside the SG include pulse width modulator, oscillator, voltage reference, error amplifier, overload protection circuit, output drivers etc.

I have made a inverter w, but the transformer is not suitable, kx3524 when I use it, the output voltage drop. The transistors heats up tremendously. After i ddi the circuit my output from the oscillator is giving me 3.

Hi Oyinz instead of using wire for transmitting data from one system to other, you use optics to do the job so that you get isolation between sender and receiver. I think this is very useful as the circuit is well explained except this function of BC Wat mosfet u use?

Come join the forum n share your knowledge. Constructors who have basic ratasheet about voltage regulators might not have made the mistake and would have completed the project successfully. Sir did ic sg is available in india sir please replay me.


What should be the number of turns for the primary and secondary of the transformer windings? Please reply to my mail.

Can i build it on 24v transformer. Sir can I use 12v amps battery for this circuit. During this period pin 11 will be low and its succeeding stages will be inactive. This circuit works well and many have successfully assembled it. When I checked the current at primary, it consumes around 8Amps.

Means we have to replace all transistors from Q4 to Q9 by two parallel mosfets irf?? Kindly expanciate this please: IC2 and its associated components produce an 8V supply from the 12V source for powering the IC and its related circuitries.

Hi Prakash all connections shown as ground to be connected to negative of the battery.

You can use 2N OR 2N instant of 2n C8 is a filter capacitor for the voltage regulator IC If I want to add more transistors to archieve for example W, which transistors would be added and doe it require more base resistors too? Because the output at pin 14 and 11 reads 3. Let me know if you have any other doubts.


Same problem with me too.

If possible please send me as early as possible. Dear Sir i made that inverter it produces a v well with neon lamp but when i connect it to a computer or LCD tv the output became not stable the frequency became not stable decrases and increases.

Sir I trying to assembling this circuit. The voltage present at the ohms resistor is enough to turn it on…. If u need the modification of the watts to watts with mosfet and also a powerful charger for it contact me on or email simeonm gmail.

SG forms the heart of this PWM inverter circuit which dwtasheet correct its output voltage against the variations in the output load. Preset R1 can be used for fine tuning of the oscillator frequency. Hello sir, I need all the details about inverter can you pls send me about that.

If we are going to get that complicated,at least make it better. Can someone answer me please I need some help here. Hello, thanks for the schematic.
