Abstract :
This paper presents the analysis of an isolated three-phase rectifier with high power factor using a Zeta converter operating in continuous conduction mode. The structure is particularly simple and robust. Its main features are one power processing stage (which can operate as step-down or step-up voltage), lower harmonic distortion of the input current, and natural isolation. The converter works with constant frequency and pulsewidth modulation. The principle of operation, design procedure, and experimental results are presented
