高效无桥双模谐振单级AC-DC变换器

This paper presents a bridgeless dual-mode single power-conversion ac-dc converter that can achieve a high conversion efficiency. By adopting a bidirectional switch, we remove a full-bridge diode rectifier from the grid side of the proposed converter, and thereby, reduce the number of components and the primary-side conduction loss. To adapt the converter to 1-kW power applications with a bidirect...
