Abstract This paper proposes a control method applying to three-phase four-switch shunt active power filter (TFSSAPF). The topology and basic operation principle of TFSSAPF are fully analyzed, followed by two DC-side capacitors voltage control methods. The dc-side total voltage is retained by controlling the active proportion of output currents. The DC-side voltage balancing is realized by adapting the direct proportion of the c-phase output current. A sinusoidal PWM method adopting the two output phase currents as instruction currents is presented. Experimental results show the validity and feasibility of the proposed method.

Key words： Power electronics three-phase four-switch inverter shunt active power filter current control DC-side voltage control
