FAJARDO-JAIMES, Arturo; OJEDA-RUIZ, Fernando; HAY-HARB, Abdel Karim  and  PERILLA-GALINDO, Gabriel. Modelling of a Rectifier with Unity Power Factor in Half Bridge Configuration. Ing. Univ. [online]. 2009, vol.13, n.1, pp.71-89. ISSN 0123-2126.

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.
