開(kāi)關(guān)電源——反激變壓器設(shè)計(jì)過(guò)程

根據(jù)功率、輸入輸出的情況，我們選擇反激電源拓?fù)洹?/p>

反激式變壓器的優(yōu)點(diǎn)有:

1、 電路簡(jiǎn)單,能提供多路直流輸出,因此適合多組輸出要求。

2、轉(zhuǎn)換,損失小。

3、變壓器匝數(shù)比值較小。

4、輸入電壓在很大的范圍內(nèi)波動(dòng)時(shí),仍可有較穩(wěn)定的輸出。

設(shè)計(jì)步驟：

1、決定電源參數(shù)。

2、計(jì)算電路參數(shù)。 

3、選擇磁芯材料。 

4、選擇磁芯的形狀和尺寸。 

5、計(jì)算變壓器匝數(shù)、有效氣隙電感系數(shù)及氣隙長(zhǎng)度。 

6、選擇繞組線圈線徑。 

7、計(jì)算變壓器損耗和溫升。
