摘　　要：提出了一种用于双凸极永磁发电机(DSPMG)的电容储能型变换器(CERC)。通过分析DSPMG的电磁特性和发电原理,提出了一种针对CERC的控制策略。与传统的三相全桥整流电路(FBR)对比,在相同的负载条件下,采用CERC电路的DSPMG发电系统的输出功率有明显提升。仿真和实验均证实了所提出的拓扑和控制策略的正确性。This paper proposes a new converter called capacitive energy recovery converter(CERC)and corresponding control strategy to enhance the power generation capability in doublysalient permanent magnet generator(DSPMG).The CERC is composed of controllable devices,uncontrollable devices and energy storage circuit.The control strategy was developed based on theanalysis of the electromagnetic characteristics of DSPMG.With the proposed control strategy,thewinding current can be promoted,thus leading to larger electromagnetic torque against the prime mover.As a result,the power generation capability of the DSPMG system with CERC is enhanced comparedwith that with traditional full-bridge rectifier(FBR).In addition,the torque ripple is relatively smaller.Both simulations and experiments were conducted to verify the validity of the proposed converter andcontrol strategy.
