This paper proposes a dc/dc converter for electric vehicle onboard chargers using a secondary resonant tank. To attain soft switching characteristics, such as zero voltage switching, magnetizing inductance has been used at the primary side of the transformer. The leakage inductance of the transformer is used as a resonant inductor on the secondary side to avoid the use of a separate inductor as resonance. The proposed converter is applicable for a wide load range. A 6.6KW prototype has been implemented for a wide range of load variations (250V, 330V, 360V, and 413V). A maximum efficiency of 97.4% is achieved at 413V.

“…T on is the active interval when the diagonal pair of switches (S 3 , S 6 ) or (S 4 , S 5 ) conduct together, and T s is the switching period, then we can derive D=2T on /T s as the duty cycle of the FB2 circuit. According to the relationship between T on and T r as shown in Table I, there are three distinct operation modes for the proposed converter [28]. In Mode 1 operation, the FB2 circuit still works in the active interval when the resonant current i Dr2 reaches zero.…”

“…Recently, several hybrid Half-bridge Full-bridge (HB-FB) converters based on "shared leg" technique have been proposed in [23][24][25][26][27][28]. Their common characteristic is that the input energy can be AEST2016 transferred to the output even in the freewheeling interval of the output inductor.…”

“…In consequence, this will increase the voltage stress across the rectifiers and may result in EMI problems. Also, a novel high-efficiency hybrid HB-FB converter with shared lagging leg is developed in [28]. In this topology, ZVS of the active switches in the lagging leg can be realized from true zero-load to full-load condition with the help of LLC resonant circuit.…”

Abstract. This paper proposes a novel soft-switching dual full-bridge converter with shared lagging leg and dual outputs in series. Resonant clamp circuits are employed across the secondary rectifiers to reduce the voltage overshoots of the secondary rectifiers, as well as extinguish the primary current during the freewheeling interval. Full Zero-Voltage-Switching (ZVS) range of the lagging leg switches can be achieved based on the parallel full-bridge configuration. The dual outputs of the proposed converter are connected in series, and the whole output voltage can be regulated within the desired voltage range by the phase-shift control. Therefore, the proposed converter would be useful for high output voltage and high power applications. Steady state operation and distinctive features of the converter are explained and verified on a 1-kW hardware prototype, and experimental results validate the feasibility and performance of the proposed converter.
