This paper is mainly concerned with the development of a new state-of-the-art prototype, high-efficiency, phase-shift, soft-switching, pulse-modulated, full-bridge DC-DC power converter with a high-frequency power transformer, which is designed for utility-grid-tied photovoltaic (PV) power inverters. The proposed high-frequency transformer (HFTR) link DC-DC converter topology is based on a new conceptual...

This paper presents two new circuit topologies of DC busline side active edge resonant snubber assisted soft-switching PWM high frequency AC link full-bridge DC-DC converter acceptable for 200V-rms and 400V-rms utility AC mains. All the power switches in the full-bridge arms and DC busline can turns on with ZCS turn-on and turn-off with ZVS and the switching power losses of all the switches can be...
