摘　　要：文章介绍了一种基于可逆SPWM变流器的新型蓄电池充放电装置,该装置可运行于单位功率因数且无谐波,并且可将电池的放电能量馈送电网;提出了一种串联双环控制方案以兼顾系统的动静态性能,控制系统的参数设计过程在Matlab/Simulink协助下进行;装置所期望的结果得到了仿真和样机实验的验证。The paper presents a novel battery charging and discharging device that is based on the reversible SPWM converter. The device can operate with unit power factor and low harmonics and feed the discharged energy back to the utility AC line. A cascade dual-loop scheme for the control of the device is proposed to achieve optimization of both dynamic and static performance of the system. The design procedure of the control system is aided by Matlab/Simulink and expected results are verified by the simulation and the prototype experiments.
