Harmonic detection in the design of active power filter is implemented using digital signal processor（DSP） TMS320F2812 in this paper.The ip-iq detecting method based on instantaneous reactive power theory is adopted as harmonic detection method,and it＇s realized on the hardware experimental platform with digital signal processor TMS320F2812 as the core using the development software CCS.Finally,the experimental results are compared with the Matlab simulation results,and the analysis results show that the harmonic current can be detected quickly and accurately in the experimental system designed,which meets the harmonic detection requirements of active power filter（APF）.
