摘　　要：通过传递函数 ,从 7个方面系统分析了影响电源高稳定度的各种因素 ,讨论了电源基本参数及它们之间的关系 ,得出影响电源稳定度的直接因素是基准电压的稳定度、分流器阻值随温度的变化、放大器输入端电压的漂移 ,间接因素是放大器本身参数的变化、放大器输入端内阻漂移、负载电阻随温度的变化。All kinds of factors are stated systematically which affect the stability of power supplies in seven aspects by way of Transmission function. The fundamental parameters of power supplies and their relations are discussed .The direct factors for stability of power supplies are obtained;they are stability of reference voltage, drift of shunt with temperature ,drift in amplifier input voltage. The indirect factors include the effect of variations in internal components, drift in voltage divider at amplifier input, effect of variation in load, effect of variation in AC input voltage. Moreover, the theory about how to research and design power supplies has been founded.
