This paper analyzed three control strategies (direct power control, per-phase harmonic reference generation method, conventional Ip-Iq method) for active power filters in three-phase four-wire systems. They were applied to a 4-leg inverter to compensate input currents of an office building. Differences in harmonic detecting and switching sequence generation… CONTINUE READING
