Abstract :This paper proposes a hysteresis band insert ignore into journalissuearticles values(HB); current control technique to reduce the power losses in a shunt active filter. During a switching period in the zero-crossing region, the inverter output current flows through a transistor. By changing the direction, it flows through the free-wheeling diode of the same switch in an inverter leg, or vice versa. The shunt active filter current typically has 6 zero-crossing regions during a fundamental frequency cycle. This paper presents a HB current control technique where there is not any switching in these 6 zero-crossing regions per period, which results in reducing the power losses. The experimental results clearly show that the power losses of the shunt active filter are reduced by using the proposed technique.
