摘要：

A two-stage isolated dual-output AD-DC converter based on three-port bridgeless power factor corrector (TP-BPFC) and its control method were proposed. With the two DC-buses, i. e. a variable DC voltage bus and a constant DC voltage bus, provided by the TP-BPFC, the total bus voltage is able to follow the variable of the DC output voltage adaptively. Therefore, the voltage gain range of the downstream DC-DC converters is reduced significantly, which can help to improve the efficiency of the downstream DC-DC converters. Topologies of the front-stage TP-BPFC and the downstream dual-input LLC resonant converter were presented. Operation principles of the TP-BPFC were analyzed in detail, and modulation and control strategies were proposed. Experimental results indicate that higher efficiency is achieved with the proposed solutions. © 2020 Chin. Soc. for Elec. Eng.
