摘要
Abstract
A quasi-resonant Flyback(QR-Flyback)converter with 65 W output was designed.The valley switching principle and the switching loss reduction mechanism of QR-Flyback were analyzed,the frequency and loss characteristics of the system under different working conditions were compared,and the advantages and disadvantages of frequency conversion control were summarized.Combined with the frequency hopping control function of the NCP1380 controller,the hardware circuit parameters of each part of the system were designed and the efficiency of the system was effectively improved.Finally,the feasibility of theoretical analysis and parameter design were verified by simulation and experiment.关键词
