A novel three-phase solid-state power factor compensation scheme is presented and analyzed. This scheme employs a PWM voltage-source inverter and has two important features. First, it can maintain a near-unity mains input power factor without sensing and computing the associated reactive power component, and second, it can substantially reduce any line current harmonics generated by nonlinear types of load. The proposed scheme is discussed in terms of principles of operation, power system design, and analysis under unbalanced operating conditions. Predicted results are verified experimentally.>
