Double-band hysteresis current-controlled single-phase shunt active filter for switching frequency mitigation
A double-band hysteresis control method is proposed for single-phase active filters. A switching device is switched during a half-cycle, while it remains either on or off during the other cycle. Switching frequency expression of the proposed method is obtained. The method ensures lower switching frequency and offers a lower current distortion. Simulation results verify the correct operation of the proposed method.
