1.光耦合测试电路断开电压上升额定值dU/dt的测量是在输入为0V时,输入信号Uin的频率增加直到晶闸管导通,然后用频率计算dU/dt,公式如下
1. Optocoupling Test Circuit Disconnection The voltage rise rating dU / dt is measured when the input is 0V and the frequency of the input signal Uin is increased until the thyristor is on, then dU / dt is calculated using the frequency as follows
