A hybrid three phase current source rectifier for high power application

This paper presents a novel hybrid three phase current source rectifier (CSR) that achieve unity power factor and low current THD for high power application. The rectifier is composed of a traditional six-pulse thyristor bridge and two controllable switches such as the isolated gate bipolar transistor (IGBT). The unity power factor and low current THD are achieved without any additional equipment which will make the rectifier complex and expensive. The simulation and experimental results are presented after introducing the schematic and the operating sequence of the rectifier.
