【Abstract】 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.更多还原
