IGBT based DC-DC converter

الملخص EN

This paper presents an in-depth analytical and experimental investigation of an indirect DC-DC converter.

The DC-AC conversion is a full bridge based on IGBT power modules, and the AC-DC conversion is done via a high frequency AC link and a first diode bridge.

The AC link, which consists of snubbing capacitors and a variable air-gap transformer, is analytically designed to fulfill Zero Voltage commutation requirement.

The proposed converter is simulated using PSPICE and a prototype is designed built and tested in the laboratory.

PSPICE simulation and experimental results are presented and compared.
