Abstract: A novel digital voltage controller for boost PFC converters is proposed in this paper. If a fast voltage compensator is applied to control the DC output voltage, the DC output voltage ripple, pulsating at twice the grid frequency, causes a third harmonic of considerable magnitude in the line current. The new controller samples the DC-bus voltage at all zeroes of its ripple, resulting in a fast voltage control algorithm that guarantees a low total harmonic distortion in the line current. The performance of the proposed voltage controller is compared to other voltage controllers, by using a prototype of a digitally controlled boost PFC convertor.
