摘要:高頻變壓器的設(shè)計(jì)是單端反激式開關(guān)電源設(shè)計(jì)的核心。如果在單端反激式開關(guān)電源中高頻變壓器的設(shè)計(jì)初步完成以后,不對高頻變壓器進(jìn)行電路的仿真而是直接進(jìn)行制作和實(shí)驗(yàn)調(diào)試,盡管最終可以得到實(shí)驗(yàn)所要求的各項(xiàng)性能指標(biāo),但是可能會(huì)花費(fèi)大量的費(fèi)用和時(shí)間。本文采用PExprt軟件對單端反激式開關(guān)電源中高頻變壓器建立模型并運(yùn)用PSPICE軟件進(jìn)行仿真,仿真結(jié)果表明本方法是可行的。

Abstract:The key in the design of the switching power supply of single-ended fly-back is the design of high-frequency transformer. After completing preliminary design of switching power 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.
