摘　　要：高频变压器的设计是单端反激式开关电源设计的核心。如果在单端反激式开关电源中高频变压器的设计初步完成以后,不对高频变压器进行电路的仿真而是直接进行制作和实验调试,尽管最终可以得到实验所要求的各项性能指标,但是可能会花费大量的费用和时间。本文采用PExprt软件对单端反激式开关电源中高频变压器建立模型并运用PSPICE软件进行仿真,仿真结果表明本方法是可行的。The key in the design of the switching completing preliminary design of switching power power supply of single-ended fly-back is the design of high-frequency transformer. After supply of single-ended Fly-back, if we plat and debug directly instead of going on simulating at first, although we can reach all the performance indices of the test, it will cost much more funds and time. This paper adopts PExprt software in modeling high-frequency transformer of the switching power supply of single-ended Fly-back, and PSPICE software in simulation. The results of simulation prove that the method is available.
