The specifications are:
Input:220Vrms@50 Hz
Output:400Vdc
pfc:0.99
THD:<8%
Switching frequency:75kHz
Ripple voltage:2.5%
Output power:2.5kW

I need some help on the soft switching circuits(ZVT) that can be used.
It would be very good if I could get some design papaers regarding it.
This is the Preoject that I am doing for my B.E. course.
Pls help
