This article describes the development of a switching power supply and its main features.To clarify its necessity and importance of the study.Analyzed with single power factor correction flyback switching power supply of their working principle,advantages and disadvantages.Traditional switching power supply is usually a large volume and weight,and the larger the ripple,stability is not high,low efficiency,and switch turn-on is the hard-switching turn-on,making the efficiency of switching power supply about a single power supply can not work long-term trouble-free can not be done to ensure that redundant system.This article discusses a single power factor correction flyback switching power supply,greatly reducing the size and weight of power supply to improve the stability of the power and efficiency.Paper first introduced the development of switching power supply technology as well as the technology involved,and then introduced at this stage of the program of power factor correction,and finally described in detail the design of the entire system.

对的，就是这个意思
