摘要

本文提出了一种基于SEPIC拓扑的单相新型交直流变换器，该变换器具有功率因数校正和输入电流整形功能。所提出的整流器是输入开关，并利用双向开关在输入。整流器在没有极性反转的情况下提供降压升压增益。该设计已单独进行，以使整流器作为降压或升压输入功率因数校正(PFC)转换器，具有接近正弦的输入电流，具有非常低的总谐波失真(THD)。采用简单的反馈控制电路进行仿真结果生成，结果表明所提出的变换器以良好的转换效率实现了上述目标。

A single phase input switched SEPIC PFC AC-DC converter

A single phase new type AC-DC converter based on SEPIC topology has been proposed in this paper which has power factor correction and input current shaping facilities. The proposed rectifier is input switched and utilizes a bidirectional switch at the input. The rectifier gives buck-boost voltage gain without polarity reversal. The design has been made separately to operate the rectifier as a buck or a boost ac-dc input power factor corrected (PFC) converter with near sinusoidal input current having very low total harmonic distortion (THD). A simple feedback control circuitry has been used for simulated result generation to show that the proposed converter achieve the above at good conversion efficiency.
