Revista da Sociedade BrasThis paper presents an analysis of a threephase rectifier with high power factor using a SEPIC DCDC converter operating in continuous conduction mode (CCM). The structure is particularly simple and robust. Its main features are: one power processing stage, which can operate as step-down or step-up converter, lower harmonic distortion in the line current and natural isolation. The converter works with constant frequency and PWM modulation. A study for steady state conditions, a design procedure, and experimental results obtained from a laboratory prototype are presented.
