I need to figure what is the best time scheme I can use it for this circuit to achieve high efficiency (soft switching)
This bidirectional DC-DC vin 60vdc and vout=600VDC Po=6Kw, so is there is any suggestion and also I need help to simulate it the circuit to figure the efficiency through simulation.

It won't do much good to calculate the efficiency of a circuit using ideal switches. :rolleyes:
the switches has the input capacitance and output capacitances ,so it is very close to the real MOSFET's ,I have question about the transformer ,if my input is 40-90vdc and output 600vdc, how can I get 40-90vdc if I have 600vdc, I did my transformer ,but I only can get 40vdc when I have 600vdc, how can I fix this problem without using boost circuit?
