摘要
分析了空间矢量PWM的基本控制原理,并将该方法应用到有源电力滤波器的主电路控制中。利用Matlab6·5·1/Simulink进行仿真,结果表明有源滤波器在任一时刻的输出补偿电流能实时地跟踪指令电流,同时与基于三角波控制的SPWM相比,提高了控制精度,滤波效果也较好。
The basic principle of space vector PWM is analyzed, and is applied to the main circuit of active power filter. Simulation by Matlab6.5.1/SI M U LI N K indicates the compensating current that APF produces can vary with its instruction current in real time. Compared to the system used SPWM based on triangular control method,it can improve the precision of active power filter,and the result of filter is better.
