Single phase rectifier circuit

摘要

A single phase rectifier circuit produces a full wave rectified voltage by rectifying an AC input voltage, couples the rectified voltage to a filter capacitor through an inductor, and repeatedly switches the sum of the rectified voltage and the voltage on the capacitor across the inductor, thereby reducing input current distortion and improving the power factor of the circuit. When the rectified voltage is of a sufficient magnitude to drive current through the inductor, switching of the capacitor voltage across the inductor can be eliminated. The switching function is performed by a half bridge boost converter.
