摘　　要：讨论了用于补偿电网电压畸变的基于数字信号处理 (DSP)的串联型电力有源滤波器 (SAPF)检测和控制策略的实现方案 ,以及该方案中的一些主要硬件结构和软件设计的控制流程。对所使用的一款DSP芯片TMS32 0F2 4 0的特点和功能进行了简明地阐述 ,论述了软件功能和设计流程 ,并详细讨论了系统中最重要的XINT3中断服务程序详细工作流程。通过与模拟控制方法对比 ,基于DSP的快速数字控制显示了其优越性和广泛的应用前景。A practical implementation of DSP based detection and control strategy for SAPF (Serial Active Power Filter) is presented, which is used in the compensation for power net voltage distortion. Its main hardware structure and software control flows are discussed in detail. The used TI's Digital Signal Processor (DSP), TMS320F240, is introduced, including its functions and specific futures. The software functions and design flows are also discussed. The interrupt server routine XINT3, which is the most important subroutine in the whole system, is shown in particular. Compared with the analog detection and control method, the digital method has shown great advantages and wide application future.
