摘要
利用气体放电管、光敏电阻和电容可以组成张弛振荡器.在特定条件下,多个张弛振荡器因相互之间的光电耦合可以达到同步.数值模拟发现2个张弛振荡器达到同步的条件与2路电路独立运行时的周期差、放电管辉光放电的持续时间和光敏电阻的时间常量有关.在此基础上模拟了多个张弛振荡电路的同步.
The relaxation oscillator was composed of gas discharge tube,photoresistor and capacitor.Multiple relaxation oscillators were synchronized due to the optoelectronic coupling between them under certain conditions.Numerical simulation showed that the synchronization conditions of two relaxation oscillators were related to the period difference,duration of glow discharge of discharge tube,and time constant of photoelectric resistance when the two circuits ran independently.Besides,the synchronization of several relaxation oscillation circuits was also simulated.
