I want to use LT8708 to design bidirectional DC/DC converter (CCM). input voltage change between 40V to 54V and output voltage should be 56V all time.
I design my circuit in LTSpice with LT8708. But it does not work. I attached pictures of my design and output voltage, M1, M2, M3 and M4 gate voltage graphes.
Could you help to solve this issue?
