| Abstract |
This paper presents two new high frequency DC-DC power converters. They are regulated at constant frequency by the pulse width modulation (PWM) technic. These converters are derived from the classical PWM phase-shifted converter by adding two impulsive current sources to achieve soft switching operation. These impulsive current sources are obtained by two new different technics, the first is built by an association of LC branches and the second one with saturable inductors. These two technics are presented and compared. The theoretical analysis and experimental results of two 2kW prototypes of the converter operating at 1Mhz are given. |
