This paper establishes a linearization current control mathematical model with fixed switching frequency for three-phase pulse width modulated (PWM) converter. The input currents are decoupling controlled in the stationary reference frame. The paper proposes a design method of inductance in AC side and voltage in DC side of main circuit. Based on the models of converter, the design method of controller is obtained. Meanwhile, the factors that influence input current harmonic are analyzed. A prototype has been implemented. The experimental results demonstrate that the designed converter has bidirectional power transmission ability with good dynamic performance. It also has the advantages of unity input power factor and low input current harmonic distortion.
