三相四线逆变器直流侧有源滤波器对不平衡负载与非线性负载的补偿

A DC-side Active Filter for Three Phase Four Wire Inverter Compensates for Unbalanced And Nonlinear Loads

本文介绍了一种三相四线逆变器直流侧有源滤波系统,这个系统对消除逆变器输入端由于不平衡与非线性负载引起的脉动电流是有效的。在电线中的零序电流也同样被消除。本系统具有响应速度快、效率高的特点。

In this paper a DC-side active filtering system for three phase four wire inverter is presented.The system effectively nullities the pulsating Currents in the inverter input terminals as a result of unbalanced or nonlinear type loads.The circulating zero sequence currents in the neutral are also nullified.The system is fast in response,high in efficiency.
