本文报导参比电压、电解池槽压均可达到±100V的恒电位仪/恒电流仪的研制和应用‘。介绍以通用集成运算放大器构成高压放大电路及高摆幅电压跟随器的原理和电路。给出了实际测试结果并介绍扩展美国PARC公司的173恒电位仪的参比电压控制范围的方法。
In this paper the development and applications of a potentionstat/galvanostat with high reference electrode potential (±100V) and high cell voltage(±100V) are described. The principles and circuit diagrams of the high voltage amplifier as well as the big swing voltage follower using general puropse IC operational amplifiers are presented. The method of expanding the range of reference electrode potential for PARC potentiostat of model 173 is shown, and the testing results are given.
