Digital control circuit for active power filter with modified instantaneous reactive power control algorithm

This paper describes the proposed active power filter with the control circuit based on the modified instantaneous reactive power control algorithm. The control circuit was realized using digital signal processor ADSP-21065. In the proposed circuit an advanced current controller algorithm realized using the digital signal processor ADSP-21065 is employed. The active power filter circuit was build and tested. Some illustrative, experimental results are also presented in the paper.
