Abstract

A novel soft-switching pulse-width modulated boost-type DC-DC converter topology is presented in this paper. The conventional boost switch is replaced by a switching cell that is comprised of two switch-diode pairs being linked by an inductor for zero-current switching turn-on. The diodes commutate the current that is flowing through the soft-switching inductor when the two switch turn-off. The capacitor is placed in parallel with the two switches during turn-off, thus providing zero-voltage switching turn-off. Simulation results are presented to support the theoretical considerations.
