This paper presents a modelling of a rectifier with unity power factor (PFC) in half bridge configuration. The proposed approach is based on the movable average technique and quasi-static process analysis. This methodology is applied to find the transfer functions that describe the dynamics of the PFC, under a cascade control structure of internal and external loops. This control requires a larger bandwidth for the internal loop. Finally, some experimental results with a digital control implemented in a digital signal processor (DSP) are presented.
