To overcome the drawback of the conventional hysteresis control, which has high switching frequency and wide frequency range in the inverter, a novel fuzzy adaptive hysteresis band current controller for active power filter is proposed. As the hysteresis band of the hysteresis current controller can adapt variety of the current and voltage deviation, the switching frequency and switch frequency range can be reduced effectively. The principle of the adaptive hysteresis band current controller is introduced, and the design of the fuzzy adaptive hysteresis band current controller is analyzed in detail. The simulation results of the conventional hysteresis control, adaptive variable hysteresis band control and fuzzy adaptive variable hysteresis band control show that the proposed method can reduce the switching frequency and narrow the variation range, and meet the requirements of the performance of high precision and real time for harmonics compensation of three-phase active power filters.
