Design and Experiment of 90W Switching Power Supply with PFC Function
摘要
Abstract
Low power factor and high harmonics are the main drawbacks of traditional AC-DC converters. A two-stage ACDC switching power supply with power function correction (PFC) function was designed to solve this issue. The former stage was power factor corrector based on boost topology with L6561 as the controller. On the latter stage, LTA705S was adopted to design a DC-DC converter based on flyback topology. The design method of the AC-DC converter was introduced in detail. Compared to the traditional one, the converter has the advantages of practicability, simple construction, low cost and small volume. Finally, a 90W prototype was built to verify the feasibility of the design.关键词
