The proposed converter achieves zero voltage switching (ZVS) switching of active switches in CCM and the diode zero current switching off which leads to negligible reverse recovery losses. The nominal voltages of the components and the energy volumes of the passive components of the proposed converter are considerably reduced compared to the conventional zero voltage transition converter. The voltage conversion ratio almost doubles compared to the conventional pulse converter. We discuss the extension of the proposed concept for the realization of multiphase dc-dc converters. The experimental results of a prototype of 1,5 kW are provided to validate the proposed concept.
Continuous conduction mode (CCM) booster converters have been widely used as front-side converters for active current input configuration [6]. In recent years, CCM surge converters are increasingly needed in high power applications such as hybrid electric vehicles and fuel cell power conversion systems. High power density and high efficiency are the main concerns in high consumption CCM converters.
