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%.
