Isolated Three-Phase Rectifier Using a Sepic DC-DC Converter in Continuous Conduction Mode For Power Factor Correction
نویسنده
چکیده
This paper presents an analysis of a three-phase rectifier with high power factor using a Sepic DC-DC 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 voltage, 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. Key-Words: Three-Phase Rectifier, Sepic DC-DC Converter, Power Factor Correction.
