A small signal equivalent circuit for a single phase rectifier in half bridge configuration, with power factor close to one is developed. From this representation an equation for the input current is presented in terms of the line voltage and the duty cycle. The frequency response is obtained for both a continuous and a discrete controller of the proportional plus integral type. The values of the total harmonic distortion and the power factor obtained from the simulation of the discrete case are compared with the implementation of a circuit based on a DSP.
