A filter bank solution for active power filter control algorithms

Abstract

This paper describes the proposed active power filter (APF) with a new control circuit based on an algorithm using a filter bank and a harmonic predictor. The control circuit was realized using the digital signal processor ADSP-21065L and FPGA circuit. In the proposed circuit transient performance of APF is improved. The active power filter circuit has been built and tested, and some illustrative, experimental results are also presented in the paper.
