Soft switched three-phase single switch boost-type rectifier
Proceedings of the Power Conversion Conference-Osaka 2002 (Cat. No.02TH8579), 2003 This paper proposes a soft-switched three-phase-single-switch-boost-rectifier circuit. The proposed circuit can perform zero-voltage-switching (ZVS) without any current and voltage sensors. For this circuit, both simulation and experiments have been performed.
