Comparative analysis of 1-phase active power factor correction topologies

Fifteen active power factor correction topologies with nonpulsated input current are presented. For convenient comparisons of current and voltages stresses as well as conduction losses, the normalized set of auxiliary parameters is derived. These parameters are shown to be simple functions of the ratio of the line voltage amplitude and DC output voltage. Since the choice of any particular topology usually depends on many application-specific factors rather than judging various power factor correction (PFC) topologies, a possibly complete class of these structures is presented, together with evaluation
