摘要
本文论述了开关电源的自激振荡和脉宽调制的工作原理,就其稳压的关键提出了新的观点;并针对维修中的难点提供了明确的思路和有效的方法。
In this paper,the work principles of self-oscillation and pulse width modulation in self-oscillating switch-modepower supply are discussed,the principal point is analysed,and a new viewpoint is proposed.As regards difficult pointsof maintenance,a reasonable train of thought and effective methods of maintenance are given.
