Abstract

A three-phase buck boost pulsewidth modulation (PWM) rectifier with a three-switch buck-type rectifier input stage and an integrated dc/dc boost converter output stage, and a three-phase boost buck PWM rectifier system formed by series connection of a boost-type rectifier input stage (Vienna Rectifier) and a dc/dc buck converter output stage are presented and comparatively evaluated. Both systems are characterized by sinusoidal input current and wide output voltage control range. The comparison is for 6 kW rated output power at 400 Vrms line-to-line input and variable output voltage 200 V 600 V and identifies the buck boost approach as significantly superior regarding the overall efficiency, the volume and weight of the passive power components, and the overall system complexity.
