本文介绍了开关电源的发展及其主要特点.阐明了其研究的必要性和重要性.分析了带功率因数校正的单片反激式开关电源的其本工作原理,优缺点.传统的开关电源通常体积和重量很大,并且纹波较大,稳定性不高,效率低,并且开关导通是硬开关导通,使得开关电源效率一般约为单片电源不能长期无故障工作,不能做到冗余系统来保证.本文讨论了功率因素校正单片反激式开关电源,大大减少电源的体积和重量,提高了电源的稳定性和效率.
论文首先介绍了开关电源技术的发展以及涉及到的技术领域,然后介绍了现阶段功率因素校正的方案,最后详细叙述了整个系统的设计.
关键词：开关电源；功率因素校正

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.
