跟踪式慢启动稳压电源的设计

The Design for Tracking Slow Starting Regulated Power Supply

本文论述了集成三端稳压器组成的负输出稳压电路,以它的输出电压作为跟踪对象,按照自控理论,进行闭环比较放大和调整,形成跟踪式正输出稳压电路,从而获得双路平衡输出的稳压电源.文中阐述了双路输出的跟踪原理,并提供了实用的设计方法及公式.

A stabilized voltage circuit composed of integrated tri-anastat negative output is introduced. With the output voltage of this circuit as the object to be tracked and by means of the theory of automatic control, the comparative amplification and regulation of the closed circuit are carried out, a tracking stabilized voltage circuit with positive output is constructed and a regulated power supply which can balance the double output routes is obtained. Not only the tracking principle of the double outputs but also the practicable methods and formulae of the design are presented.
