摘要：本文提出了一種基于磁放大器的多輸出開關(guān)穩(wěn)壓電源設(shè)計方法，據(jù)此設(shè)計出了具有實用價值的新型開關(guān)電源。本文分析了電路的穩(wěn)壓及限流原理，同時對系統(tǒng)的穩(wěn)定性進行了分析，且提供了一些關(guān)鍵參數(shù)的設(shè)計與計算。實驗證明：該穩(wěn)壓電源的效率達85％，電壓穩(wěn)定度可達98.5％。

ABSTRACT: This paper puts forward a multi-output-voltage’s design on the basis of a magnetic amplifier, and we design a novel practical valued switching power according to the theory. The paper analyses the voltage-stabilization and current-limitation theory of this circuit, moreover discusses the stabilization of the whole closed-loop system, some critical parameters are designed and calculated. Experiments prove: the efficiency of the voltage-stabilization power is 85%, and the stability is up to 98.5%.
