摘　　要：程控交换机电源性能的好坏直接影响通讯质量,它要求电源具有稳定度高,小于2%的电压变化率,纹波系数小等特点.煤矿企业使用的小型程控交换机对电源还有宽的电压适应范围,安装使用方便,完善的保护功能等特殊要求.单片开关电源L296恰恰满足了这方面的要求.The characteristic of power supply is a main factor that effects the quality of communication.The power supply should have high voltage stabilization,lower than 2?percent of voltage changing rate and smaller coefficient of wave.There must be special demands to power supply when it be used in coal mines.The single chip L296 switch power supply can satisty the demands.
