Abstract

In this paper, the authors propose to study the use of several zero-current-switched quasi-resonant power converters (flyback, SEPIC and Cuk) with a half-wave switch, working as power factor preregulators (PFP) with voltage-following control. The analysis carried out demonstrates that these power converters show excellent characteristics for obtaining high power factor without using any input current feedback loop. They also allow high switching frequency operation because they integrate transformer and rectifier diode parasitics into the power topology
