Research on Shunt Active Power Filter Based on Soft-switching Technology

本文讨论了并联型有源电力滤波器(APF)的系统构成,并且根据谐振原理将软开关技术应用于有源电力滤波器的主电路中,可进一步降低主电路开关管的损耗,提高有源电力滤波器工作的可靠性。在控制策略方面,主电路部分采用滞环与空间矢量相结合的控制方法,软开关部分的控制与主开关器件的控制相配合。最后在MATLAB平台上建立整个系统的仿真模型。

This paper discusses the system structure of shunt active power filter. According to the principle of resonance, soft-switching technology can be applied to the main circuit of active power filter, which can reduce the waste of the main circuit switch tube and improve the reliability of active power filter. In the control Strategy, the main circuit based on hysteretic and space vector control, and soft-switching match to this way. Finally, the system simulation model is established on the MATLAB.
