During the processing of harmonic current detection and restraining
the output of digital processor has a certain delay due to A/D conversion
amount of harmonic detection algorithm and control algorithm.It’s hard to fulfill the requirements of real-time filter.Backward interpolation has advantages of easier calculation and fewer errors.It can improve the real-time of APF effectively by using backward interpolation to predict harmonic.The simulation results show the effectiveness of this algorithm.
