摘　　要：换器型稳压电源分为脉冲宽度调制(PWM)型和脉冲频率调制(PFM)型两种,前者在我国已有较多应用,后者应用尚少。笔者曾参与研制成功一种利用高频型快速晶闸管实现的PFM型直流稳压电源,已付诸实际使用。文中对其进行理论分析,以做便得出其设计方法。There are two kinds of converter regulated power supply ： pulsc-width modulation （PWM） and pulse-frequency modulation （PFM）. The former has been applied widely;the latter, bowever, has little application in our country. The author bas joined in and auccessfully accomplished a PFM DC regulated power supply using high-frequency fast switching thyristor, which has been adopted in practical application. This paper introduces its theoretie analysis,and design method.
