摘要：
A Three-Switched-Networks SEPIC, PFC 350W Rectifier, utilizing magnetic integration at input and operating fz CCM for every input and load conditions, is presented. The proposed Off-line 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 and procedures are described and some basic results from a laboratory prototype are also given.
