As an alternative to two-stage cascaded AC-DC converters, the paper presents a single-stage three-phase rectifier with input/output isolation. The rectifier contains five active devices driven by a simple PWM controller. The proposed converter operates in DCM and provides improved input current spectrum. Zero-voltage switching for all active devices and diodes is implemented in the suggested converter with low effort. Operational principle and design, as well as experimental results obtained from a 5 kW prototype, are discussed.
