Interleaved active clamp flyback converter
November 18, 2019 - 6:10pm

as per the figure we provides a dc voltage as a input to the interleaved active clamp flyback converter block, provide a PWM signal to the MOSFET which is in interleaved block for switching purpose. PWM signal is generated by the microcontroller which has a fix frequency 57 KHz and 50 % duty cycle then we got a output like triangular waveform. actually we will need a output like a given figure so which type of PWM output will be provided to the switching MOSFET, so we got proper output of the interleaved active clamp flyback converter. https://drive.google.com/open?id=1bfDUd32Z8ZukB1b3RUox9aMBIgb300zJ

What is inside the switching block ?

Hey Ashvin, its hard to help without knowing your switching topology. What circuit is inside this "Interleaved block"? 

During a DC to AC conversion, it is normal to get a square wave or triangle wave. Are you trying to design a pure sine wave inverter?

Also How did you measure this waveform? During no load? 

You can either use the SPWM technique or a transformer to get a sine wave
