摘要

A 17lree-Switched-Network* SEPIC, PFC 350W Rectifier, utilizing magnetic integration at input and operating in CCM for every input and load conditions, is presented. The proposed Offline Switcher shows convenient energy storage at low voltage,good load regulation, easy to implement output over-voltage and short-circuit protection, low inrush current and no heavy input filter. For all the above reasons it assures high efficiency and low cost. Operation of the converter, most design rules andprocedures are described and some basic results from a laboratory prototype are also given.
