Isolated three-phase rectifier with high power factor using the zeta converter in continuous conduction mode

摘要

This paper presents the analysis of an isolated three-phase rectifier with high power factor using a Zeta converter operating in the continuous conduction mode (CCM). The structure is particularly simple and robust. Its main features are: one power processing stage; lower harmonic distortion in the current; and natural isolation. Its principle of operation, design procedure and experimental results are presented.
