This paper describes a high-frequency soft-switching dc-dc converter with simple energy recovery capacitor snubber on the secondary side. The presented full-bridge removes main drawbacks of classic Phase Shifted PWM (PS-PWM) converter, e.g., circulating current flowing during free-wheeling interval and dependency soft switching load current. utilizes topology pulse-width modulation centre-tappe...

The design of a 1000-W universal AC input to 48-VDC output power supply is described. This power supply consists of an interleaved Power Factor Correction (PFC) stage and a phase shifted full bridge (PSFB) DC/DC converter, all controlled by a single UCD9501 DSP controller. The design steps leading to the development of the control effort for the DSP are outlined and compared to the equivalent s...

37 Abstract— This paper presents a comparison of half bridge and full bridge isolated, soft-switched, DC-DC converters for Electrolysis application. An electrolyser is a part of renewable energy system which generates hydrogen from water electrolysis that used in fuel cells. A DC-DC converter is required to couple electrolyser to system DC bus. The proposed DC-DC converter is realized in both f...

The main objective of this concept is to examine the operation of fundamental buck-based three-phase singlestage ac–dc full-bridge converters. In this concept, the operation of this fundamental converter is explained and analyzed, and a procedure for the design of its key components is derived and demonstrated with an example and general concluding remarks comparing Buck-Based and Boost Based t...

A compact dc/ac inverter for automotive is presented and experimented. The proposed inverter consists of fall bridge inverter and a new ZVCS quasi-resonant push pull dc/dc converter. The new dc/dc converter converts input 12 V (from battery) to high voltage (about) 200V at very high conversion efficiency without regulation. The high voltage will be converted to ac at the desired voltage and fre...
