“…E sw (23) in which E sw indicates hard switching energy losses in each switching cycle, E oss is the energy stored in the output capacitance C oss that needs to turn off the switch [46], Q c is the capacitive charge that is required to turn off the diode, and V re,D is the reversed voltage across the output diode. In (22), the output diode switching losses are ignored since the converters are in the DCM.…”

“…Most bridgeless topology evaluations do not offer quantitative comparisons in terms of efficiency, cost, and volume, which are also strongly related to component parameters [3], [22]- [24]. For example, in [3], [22], [23], the boost bridgeless topologies are evaluated based on their operation modes and topology features. In [24], several boost type PFC converters are explored and compared under different power levels.…”

Compared with conventional power factor correction (PFC) topologies, although dual-converter cell-based bridgeless topologies usually have higher efficiency, most of them suffer from high component counts. Thus, this paper proposes general topology simplification methods for these topologies. Besides, several selected converter cells are exemplified to show the specific topology simplification processes and the performance of the resultant simplified topologies is reviewed. Meanwhile, based on the same design specifications, in order to provide an unbiased quantitative topology comparison in terms of power loss, cost, and volume, this paper introduces a consistent component databasebased design procedure with electrical, thermal, and cost models. As case studies, the conventional and two selected bridgeless buck-boost type topologies are compared by following the design procedure. The comparison results are analyzed to provide a reference for topology selection. Three prototypes are built and tested to verify the theoretical analysis.
