Realization of control algorithms for active power filter by means of DSP TMS320F2812

The paper describes the active power filter structure, control algorithms and methods for filter current regulation. Firstly, there is described the structure of parallel active filter power part, their resonant DC - link and structure of active filter general conception. Then there is described the control algorithms and methods for filter current regulation. The paper is mainly orientated to control algorithm realization, used for DSP TMS320F2812 implementation. Used control unit was designed by use of development DSP kit. Reached results that are presented in the paper are simulation and practical realization results.
