abstract = "This paper presents a circuit structure for electric vehicle battery chargers. The AC-DC stage employs boost APFC circuit which can convert 220 V AC voltage to 400 V DC voltage with very low-input THD. In order to convert 400 V DC voltage to 44–64 V, an improved phase-shift full-bridge soft switching ZVS PWM converter added by two clamping diodes and one resonant inductor is presented. All main switches of the improved converter can achieve ZVS at full load variation, and the oscillation and voltage spikes across the output rectifier diodes at the secondary side of the transformer can be significantly reduced. Thus, the charger system has high efficiency and compact structure merits. Performance of the proposed circuit is verified by experimental results for a 1.5 kW prototype.",
