摘要
本文提出了一种多输出线性直流稳压电源的设计。该直流供电电源设计以固定式和可调式集成稳压器件为核心,可以提供多个固定的直流电压输出,和一个电压连续可调的直流电压输出。该电源采用了双重过载保护电路和抗干扰技术。经对电源样机的实验测试,该电源性能好、工作可靠,可以满足用于压电传感器的电荷放大器对多种直流电的需要。
A design of linear multi-output direct current voltage -stabilized power supply is given in this paper .The power supply is based on fixed and adjustable voltage -stabilized ICs. It has multiple fixed DC voltage outputs and a voltage-adjustable DC voltage output. A double-protect electrical circuit for preventing over loading and anti-interference techniques are adopted . The test for the prototype has proved that this type of power supply has reliable and outstanding performances, and can meet the need of the charge amplifiers of piezoelectric transducers for the multiple DC supplys.
