Comparative study of high power factor boost rectifiers in continuous conduction mode

Abstract

This work presents a comparative study of singlephase boost-based ac-dc converters applied to power factor correction. Three structures are chosen for this purpose and analyzed in detail e.g. the classical boost converter, the bridgeless boost converter, and the boost converter based on the three-state switching cell (3SSC) operating in continuous conduction mode (CCM). The aforementioned topologies are briefly revised so that they can be properly designed and validated considering results obtained from simulation tests, where aspects such as the input current, regulated output voltage, harmonic content, and dynamic response are investigated.I.
