This paper proposes a new topology for a pulse width modulation (PWM) rectifier which can achieves both sinusoidal input current on the ac side and ripple power decoupling on the DC side without additional switches. The AC inductor of the conventional H-bridge circuit is divided into two parts and only an auxiliary decoupling capacitor is added in the proposed circuit. Control scheme is also proposed for the circuit working as unity power factor rectifier. Compared with other decoupling circuits, this circuit has the same advantage such as high power density. Due to no additional switches, the proposed circuit has higher efficiency. Effectiveness of the circuit is validated by simulation.
