Abstract

This paper presents a new high frequency DC-DC power converter. It is regulated at constant frequency by the pulse width modulation (PWM) technique. This power converter is derived from the classical PWM phase-shifted power converter by adding two impulsive current sources to achieve soft switching operation. These impulsive current sources are obtained by a new technique which consists of saturable inductors. The theoretical analysis and experimental results of a 2 kW prototype of the power converter operating at 1 MHz are given
