Abstract :
In this paper, a comprehensive efficiency evaluation of several single-phase bridgeless Power Factor Correction (PFC) boost rectifier topologies is conducted. Both two-level and three-level bridgeless PFC boost rectifier topologies are considered; including paralleled and interleaved variants of each. To improve efficiency, a three-level bridgeless PFC boost rectifier with an AC switch is proposed. Loss analysis of the topologies are provided, which shows the advantage of three-level converters and interleaved systems in achieving high efficiency.
