This work presents a new multilevel unidirectional single-phase PFC rectifier topology well-suited for applications targeting for high efficiency and/or high power density. The characteristics of this rectifier topology, including the principles of operation, modulation strategy, feedback control scheme, and dimensioning equations are described in this paper. Finally, a 3 kW laboratory prototype is constructed and used in order to verify the characteristics of the new converter.
