摘要
单片函数发生器ICL80 38在PLL中作为压控振荡器 (VCO)产生同步等幅正弦波 ,可作为静止变频器的基准信号源。此方案成功地应用于变电站接地电阻测量变频电源控制电路中。
The single chip function generator ICL8038 can get synchronous sine wave of constant amplitude in PLL as voltage control oscillation(VCO),which is a basic signal source of static frequency converter.This project is applied to the control circuit of the frequency converter power source of for measuring ground resistance in an electric substation.
