Hi,
I have tried to simulate a Phase Shifted Full Bridge Converter but it is giving me results which I cannot understand. Can someone help me? I have attached the simulation file. Switching frequency = 150kHz; Phase shift between the two legs - approx 20% of Ts. Value of L = 0; (for ideal IGBTs) and L = 1e-6; (to introduce turn on and turn off delays)

Put diode bridge at the output instead of single diode and try.
