I have problem View attachment 118309with the simulation of phase shift full bridge DC-DC ,bidirectional ,can some one check the simulation file

What seems to be the problem?
Edit:
I mean I can see some problems like high current due to cross conduction and lack of any resistance in the load, but I'm not sure what is bothering you.

This DC-DC bidirectional power supply ,input 80vdc and output 500vdc , i need to figure the best timing i can use to improve the efficiency

and also i need to do control for te phase shift to be regulated

Way over my head to design it, but if your going to optimize it you will need to use actual components instead of Spice switches.

in LTspice if I use MOSFET ,the simulation time will be too long ,that why I use switches and I add CISS and Rg and COSS to the switch
