摘要：

The hard-switching operation and the intensive stress of switches are two common problems in current Swiss rectifiers, which seriously affect the characteristics of the power rate and the power density. In order to improve the power density in high power applications, a novel isolated Swiss rectifier, named Swiss phase-shift full-bridge rectifier (SPFR), is presented. A novel modulation strategy is also proposed to realize the soft switching in SPFR. The principle of the soft-switching is discussed in detail. The characteristic of the soft-switching in SPFR are verified by the experimental results of a prototype rated at 10kW.
