摘要
针对并联型有源电力滤波器(APF)采用三电平PWM结构。分析了三电平逆变器中产生中点电位波动的原因。为解决传统控制直流侧电压存在超调量静差较大的问题,提出了一种解决方案。最后通过仿真和实验验证了该算法的可行性和良好的控制效果。
The structure of three-level PWM is applied to the shunt active power filter（APF）.The reason which the three-level inverter midpoint potential volatility inherent problems is analyzed.In order to solve overshoot static error larger issues existing in the traditional DC voltage control,a solution is proposed.The waveforms show that the algorithm has good control effect and the experiment verify the feasibility of the algorithm.
