摘　　要：设计了一种基于L6562的反激式开关电源,并阐述了该电源的工作原理,对相关参数进行了计算推导。利用MOS管自身的输出电容与变压器原边电感产生谐振,通过适当控制实现了开关管的零电压导通。最后制作了样机,通过实验验证该LED电源与传统的反激式开关电源相比,能将开关损耗有效降低,并提高了效率。Design of flyback switching power supply based on L6562 D, and explain the working principle of the power supply, the relevant parameters were calculated. Using MOS tube own output capacitance and inductance of the transformer primary side resonance, through appropriate control, the zero-voltage switch turn-on was realized.Finally compared to traditional flyback converter, a prototype was produced, then the switching loss could be effectively reduced, and the efficiency could be improved.
