Abstract

A new soft switching isolated bi-directional phase shifted pulse width modulation (PSPWM) DC/DC converter is presented. Due to the use of the energy recovery snubber, the isolated bi-directional PSPWM DC/DC converter has a significant reduction of switching losses in the switching devices of the primary and secondary side bridge, respectively. The proposed soft switching bi-directional PSPWM FB DC/DC converter provides an energy recovery snubber which consists of two fast recovery diodes, a resonant capacitor and a resonant inductor. The complete operating principles and simulation results are presented
