Bridgeless PFC Topology Simplification and Design for Performance Benchmarking

Abstract

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.

High-Performance Control Simulation of PFC Converter for Electric Vehicle Charger

“…In order to reduce losses and improve the efciency of the whole PFC circuit, more and more people have begun to pay attention to new topologies in recent years [12]. Among these topologies, the bridgeless PFC topology has received extensive attention due to its simple structure, reliability, and less peripheral devices in the control circuit [13], as shown in Figure 1.…”

A Review on Power Electronics Technologies for Power Quality Improvement

“…The GaN characteristics, such as low on-resistance, fast switching speed, and, especially, the zero reverse recovery loss, turn possible the totem-pole topology with over 99% conversion efficiency. Other single-phase PFC converter topologies were reviewed in [324,325].…”

Mission Profile Based Reliability Analysis of A Bridgeless Boost PFC

“…As can be seen in Table I, those key components, along with the heatsinks, satisfy the sizing criteria, e.g., calculated junction temperature T cal,S ∈ 100 ± 2 • C for switches. In fact, these critical components are selected from a component list based on the consistent design procedure detailed in [21]. Based on Table I, Fig.…”
