摘要
讨论了采用同步PI控制和SVPWM技术的脉冲整流器在能量回馈装置中的应用，基于数字信号处理器TMS520F2812设计了控制电路。实验结果表明，这种同步PI控制脉冲整流器具有良好的动态响应能力，馈网电流接近正弦，功率因数近似为一1．0，且谐波满足lEEE一519标准。
This paper presents the application of synchronous current PI control and SVPWM PWM rectifier in electric dynamometer. The control circuit is implemented based on digital signal processor TMS320F2812. Experimental results show that the PWM rectifier under synchronous current PI control has high dynamic performance. The line-current is close to be sinusoidal and the power factor is approximately -1.0. Also the harmonics meet IEEE-519 standard.
