摘要: This paper describes an original topology for a stepdown DC-DC converter. converter is resonant with zero voltage switching and current switching. Regulation of the done by PWM variable frequency; this provides good regulation, from no load to full load. A prototype was built output power 4 kW, input range 280 VDC 440 VDC, 14 VDC. The has efficiency 92-94%, cost effective, fit high applications. authors suggest that presented better alternative typical phase-shift topology, additional advantage being bi-directional
