This paper presents new three-level unidirectional single-phase PFC rectifier topologies well suited for applications targeting high efficiency and/or high power density. The characteristics of a selected novel rectifier topology including its principles of operation, modulation strategy, feedback control scheme, and a power circuit design related analysis are presented. Finally, a 220-V/3-kW laboratory prototype is constructed and used in order to verify the characteristics of the new converter, which include remarkably low switching losses and single ac-side boost inductor, that allow for a 98.6% peak efficiency with a switching frequency of 140 kHz.
