摘　　要：针对大功率高频开关电源的输入整流级产生的无功和谐波等电能质量问题,研究了一种基于电流型PWM整流的高频开关电源。在分析电流型整流器的单相等效模型的基础上,提出了一种基于负载功率前馈的闭环控制方法,可实现系统的快速、高效整流。针对多台开关电源的并联均流问题,提出了一种阻抗匹配的自动均流控制方法,实现多台电源的稳定运行,通过仿真与实验验证了控制方法的正确性。Power quality problems such as reactive and harmonic currents generated by input rectifier were considered. A high-frequency switching power supply based on current-source PWM rectifier was researched. Based on the single-phase equivalent model of current-source rectifier, a closed-loop control method based on load power feed-forward was proposed. Fast and efficient rectification was achieved. As for current-sharing problem of multiple-parallel power supplies, a current-sharing control method based on impedance matching was presented. A stable operation of multiple power supplies was achieved. Finally, the correctness of control method was verified.
