提出了一种适用于中压场合的单开关、单级、三相AC-DC降压-升压变换器。基本关系，管理稳态转换器操作的建立，确认使用PSCAD/EMTDC仿真，并通过实验证实。仿真和实验结果表明，该变换器在降压和升压模式下具有良好的动态性能，输入功率因数接近单位。
A single-switch, single-stage, three-phase ac-dc buck-boost converter suitable for medium-voltage applications is proposed. Basic relations that govern steady-state converter operation are established, confirmed using PSCAD/EMTDC simulations, and substantiated experimentally. Simulation and experimental results establish that the proposed converter has good dynamic performance in buck and boost modes, with near unity input power factor.
