Abstract
A bridgeless interleaved power factor correction (PFC) circuit using a single PFC choke having four windings formed on a single core to form the four input inductors of the PFC circuit. An AC-to-DC converter constructed using the bridgeless interleaved PFC circuit achieves high conversion efficiency with high power factor and low total harmonic distortion. Furthermore, the size of the PFC circuit is reduced by using a single PFC choke with quad-winding.
