摘　　要：电源是各类电子设备的重要组成部分。设计了以SG1844控制器为核心的单端反激式开关电源的电路,给出了系统的变压器、电压环以及电流环的主要参数设计方法,建立了模型并运用ORCAD/PSPICE对开关电源的整体电路进行仿真实验,结果表明该设计的可行性。Various types of electronic equipment, power supply is an important part. SG1844 controller is designed with the core of single- ended flyback switching power supply circuit, given the system transformer, the voltage loop and current loop of the main parameters of the design method, a model and the use of ORCAD/PSPICE for the overall switching power supply circuit simulation results show the feasibility of the design.
