The problem is there is no feedback. And probably very high frequency high voltage output. I have made several similar boards from op-amps mosfets and PC PSU power transformer like yourself but have added shooting at the output and feedback for stable voltage output and adjustment. Your board looks very nicely build by the way 👍.

[@yonnou7846]

thank you for sharing the file

[@PhdHung]

[@GhostsOfSparta]

The IC already has inbuilt totem poles at output stage no need to add extra in the circuit.

[@PhdHung]

Yes, that's true if you use real SG3525. However, with SG3525 from china, you need to add totempole driver.

[@GhostsOfSparta]

@@PhdHung Ohh. How to know if it's fake without oscilloscope? Otherwise it's as good as TL494.

[@PhdHung]

Very simple, use a 5 Ohm / 1W load resistor connected to the output PWM pin. If the current is less than 500mA. SG3525 is fake. Normally, the SG3525 I bought in China only has a current of about 100mA.

[@PhdHung]

With 500mA, you can only drive up to 4 mosfet IRF3205 at 70Khz. If you want to use more mosfet, you need an external totempole driver.

[@GhostsOfSparta]

What values of Rt, Ct, and Rd did you use for 50Hz frequency? I am not able to get reliable frequencies below 1kHz using 3525.

[@superkhan1934]

Excellent work....I hv a question sir...where to connect Protect Pin 3 and pin 4 of this module

[@PhdHung]

Connect it to a shunt resistor. When overloaded, there will be a voltage drop on the shunt resistor. When this voltage is greater than 0.6V, Opto will work and the circuit will turn off.

for installation of protection blocks whether connecting directly to the voltage of a 400volt capacitor, please explain

[@zarzisrony4656]

Why pin 4(Oscillator Output ) is connected with pin 15(Vcc)?

Pin 3 and Pin4 are not connected to the PCB, you have to break its pins.

hi there, i just build this circuit but most of the time the pwm shutdown after powering it with or without load, no voltage output at pin 11 & 14, try new IC with same result i use only 4 pin from the module, VCC,GND, PWM 1 & 2 FYI i just try to light up 15W filament bulb i don't have 0.47uF cap so i use 100nF(104) for pin 2,15 and pin 8 coz that's all i got at the moment CT 1nF(102), RT 2K in series with 10K trimmer,RD 47Ohm other component is exactly as schematic, drive 2x IRF44ZN with 10K resistor as pull down resistor any solution ?
