Noncausal current predictor for active power filter

This paper describes the proposed active power filter (APF) with a new control circuit based on an control algorithm using a non-causal current predictor. The control circuit design incorporates 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.
