摘要

介绍了一种新型的串联谐振变换器的基本特性，以及采用该变换器的2.7 kW整流器的基本特性。与传统的串联谐振变换器相比，SRCBDC具有显著的优势，尤其适用于整流器。SRCBDC的优点如下:即使f/sub r/>，也可以在零电流下切换

A 100 kHz, 2.7 kW rectifier using a series-resonant converter bypassing discharge current

The fundamental characteristics of a newly developed series-resonant converter bypassing discharge current (SRCBDC) and of a 2.7 kW rectifier using this converter are described. The SRCBDC has significant advantages over conventional series-resonant converters and is particularly useful for application to rectifiers. The advantages of the SRCBDC are as follows. It is possible to switch at zero current, even if f/sub r/<2f/sub s/ (where f/sub r/ is the resonant frequency and f/sub s/ is the switching frequency); bypassing discharge current away from a transformer makes it possible to use MOSFETs as switching devices; switching frequency variation is less than that of a conventional series-resonant converter so it is possible to use IGBTs (insulated-gate bipolar transistors) as switching devices even if f/sub r/=100 kHz.<>
