Hi,

Can you please explain the max and min switching freq. for both forward mode and reverse mode?

Can you please show gate driving signal waveforms for both forward mode and reverse mode?

Can you please show the control block diagram?

There is no frequency adjusting and operating with fix frequency.

It is operating as below Figure (a)

For now, we haven't develop control loop in this design.

Could you please explain the idea behind to use fix frequency?

Hi Gokhan,

At the resonant frequency, the converter will hold the best efficiency. When the switching frequency is far away to the resonant point, its efficiency will be dropped sharply.

As we will have BUCK stage to cover the voltage and current regulation, we would like to keep the front stage operating at the sweet point of resonant frequency.
