Abstract
This work presents a unidirectional three-phase PFC rectifier well-suited for application targeting high efficiency and/or high power density, such as DC-type electric vehicle chargers. Herein, a quasi-single stage AC-DC converter is proposed where a conventional three-phase DELTA-switch voltage source rectifier is cascaded to a PWM interleaved buck-type DC-DC converter by means of a low energy storage DC-link. The characteristics of the presented power electronics, including the principles of operation, modulation strategy, suitable PWM control scheme, and dimensioning equations are described in this paper. The presented circuit is benchmarked against other solutions for a 50 kW power capability battery charger. The results show a superior power efficiency of the proposed system.
