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.

You need to modify the PWM duty cycle in such a way that it produces the desired waveform. You can't just keep it fixed at 50% duty cycle. Alternatively, you can close a control loop and just modify the reference in a way that creates the sine wave.

Are you asking a question or just trying to shock us with the latest technology trends? Don't put your remaining finger on the high voltage leads.

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

Never mind "latest technology trends" - surely, creating a sine (or other) wave using PWM is a basic technique that has been around for decades ... ?

 

 

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
