開關(guān)穩(wěn)壓電源

摘要：使用PWM控制器SG3524設(shè)計并制作了一種推挽型DC/DC變換器，輸出電壓可在30～36V可調(diào)，系統(tǒng)效率可以達(dá)到92%。整個變換器由C8051F020型單片機作為控制核心，可以將輸入輸出電壓、電流和系統(tǒng)效率顯示出來，并可以對輸出電壓預(yù)設(shè)和步進(jìn)調(diào)整，還可以實現(xiàn)過流保護(hù)和過壓欠壓指示，完成了基本部分和發(fā)揮部分的所有要求。

Abstract: Using PWM controller SG3524, we designed and produced a push-pull DC/DC converter ,whose output voltage can be adjustable from 30V to 36V .The system efficiency can reach 92%.The converter uses C8051f020 as a controller .The input and output voltage ,input and output current ,and system efficiency can be displayed . It also has over-current protection , over-voltage and under-voltage instructions.  You can preset and step the output voltage. The converter realizes all the basic part and exertion part requirements.
