Active power filters are advanced devices in the field of applied power electronics. An important aspect of the performance of Active power filter concerns the control strategy used. DSP perform fast and accurate calculations, flexible program capability, and abundant peripheral functions, so applications of DSP in Active power filter digital controls will be extensive. This paper presents control strategies based on DSP for Active Power Filter. This paper also describes the device of control system based on TMS320F240 for Active Power Filter. In chapter one, the paper discusses the digital control technology for Active Power Filter, and gives a more detailed discussion of DSP controller design. In chapter two, the system structure and working principle of APF are introduced also the affection on compensation precision when main parameters of APF vary are studied. In chapter three, the hardware design of DSP control system for Active Power Filter is presented. In chapter four, the software design of DSP control system for Active Power Filter is presented. The main program flow chart, harmonic current detecting method, soft start, and DC bar voltage control are introduced detailed. Chapter five introduced the 15kVA APF test system. Conclusions and prospects for DSP controllers applied in APF are given in the last chapter.
