Implementation of a new active power filter control algorithm in time domain for selected current harmonics

This paper presents a specific time domain algorithm for controlling an active power filter and its implementation. The proposed control algorithm is characterized by independent current control in each phase and the ability to select specific current harmonics generated by the active power filter. The chosen method of determining harmonics allows compensating for time delay in the control system. This ensures high harmonic reduction effectiveness and stable system operation in a wide frequency range, both in open and closed-loop control. The algorithm was implemented and tested in a real system with a digital controller based on a multi-core DSP microcontroller.
