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.

Hi,

To get the output as shown in the figure (fully rectified sine wave), please follow the steps,

1) Use a proper filter circuit at the output (preferably LCL).
2) The PWM duty has to varied from minimum to maximum to and maximum to minimum at every each half cycle.
