description LLC resonant converter is widely used due to its soft switching, high power density and high efficiency. To incorporate the merits of the LLC resonant tank into a three-phase single-stage AC/DC converter, this paper proposes a three-phase single-stage AC/DC converter based on Swiss rectifier and three-level LLC topology. It takes advantage of the high-efficiency Swiss rectifier to convert three-phase AC voltages into three variable DC voltages and interface a three-level LLC resonant circuit. With help of the LLC resonant tank, all the high-frequency three-level switches achieve soft switching. To both regulate the output voltage and achieve three-phase power factor correction, the frequency modulation in combination with the duty cycle control strategy is employed by splitting the resonant current into three parts and then forming three phase sinusoidal currents. The proposed converter's detailed operation principles, steady-state characteristics and design considerations are given. Finally, a 10 kW experimental prototype with three-phase 220Vac inputs and 500Vdc output is built to verify the effectiveness and feasibility of the proposed topology and its control strategy.
