Abstract
In recent years, soft-switching resonant type DC-DC converters using the latest power semiconductor switching devices have attracted their special interests in the specific power electronics application fields. This paper describes the zero-current soft-switching (ZCS) DC-DC converter topology incorporated resonant switches into the conventional series resonant half-bridge inverter circuit configuration. The proposed soft switching DC-DC converter can effectively operate under a ZCS transition on the basis of a fixed frequency and phase-shifting control strategy for output voltage regulation. The trially-produced resonant type DC-DC converter using B-SIT is presented for the switching DC power supply and its performances are discussed from a practical point of view.
