摘要
介绍了补偿式交流稳压器的组成和工作原理,对其中所用线性功率放大器的功放管管耗作了较详细的分析。提出一种两级自动切换供电方法,用此方法可使功放管最大管耗降低44%左右。
The construction and principle of a compensative A. C. regulated power supply are presented. The power dissipation in the power transistors of power amplifier of this power supply are analysed and a two-level autoswitching power supply method are presented. The maximun of the power dissipation in the power transistors will be reduced about 44% by using this method.
