摘要
针对带桥式整流阻性负载的并联型有源电力滤波器(APF),按照谐波次数分解,从理论上推导出网侧电流畸变率与电路参数之间的关系式。研究了控制环路延时及死区环节两者对补偿效果的影响,并通过Matlab软件建立模型证明了理论分析的正确性。最后在一台15kVA三相四线的并联APF样机上验证了该方法的实用性和有效性。
Based on the shunt active power filter（APF）with resistive load and breaking up harmonic orderr,elationship between grid total harmonic distortion（THD）and system parameter theoretically is deduced.Besidest,he influence of control delay and dead-time to compensation accuracy is studied.Simulation and experimental results in a 15 kVA APF prototype demonstrate the effectiveness and efficiency of the proposed method.
