1.2电路拓扑的选择 

开关电源一般采用单端正激式、单端反激式、双管正激式、双单端正激式、双正漫式、推挽式、半标、全标等八种拓扑。其中双管正激式、双正激式和半桥电路的 

开关管承压仅为輸入电源电压,60%降额时选用600V的开关管比较容易,不会出现单向偏磁饱和的问题,这三种拓扑在高压输入电路中得到广泛的应用 

1.3功率因数校正技术 

开关电源的谐波电流污染电网,干扰了其它共网设音,还可能会使采用三相四线制的中线电流过大,引发事故,解决途径之一是采用具有功率因素校正技术的开关 

电源。

在中小功率的电源中,电流型PWM控制是大量采用的方法,在DC-DC変换器中輸出纹波可以控制在10mV,优于电压型控制的常规电源。 

硬开关技术因开关损耗的限制,开关频率一般在350kHz以下开关技术是使开关器件在零电压或零电流状态下开关,实现开关损耗为零,从而可将开关频率提 

到光赫级水平,此技术主要应用于大功率系統,小功率系统中较少见。 

15元器件的选用 

器件直接决定了电源的可靠性,元器件的选用是非常重要。元器件的失效主要集中在以下四点:制造质量问题、器件可靠性的问题、设计问题、损耗问 

题。在使用中应对此予以足够重视。 

6保护电路 

为使电源能在各种恶劣环境下可靠地工作,应在设计时加入多种保护电路,如防浪涌沖击、过欠压、过载、短路、过热等保护电路
