描述

因此常將此參數(shù)標(biāo)記為通態(tài)平均電流IT（RMS），指可控硅元件可以連續(xù)通過的工頻正弦半波電流（在一個周期內(nèi)）的平均值，而此時流過G、K兩極的電流即為門極電流IG（Gate Current），這個門極控制電流不應(yīng)超過門極大峰值電流IGM（Forward Peak Gate Voltage）當(dāng)VAK是交流電源的負(fù)半周時，可控硅因為A、K兩極加反向電壓而阻斷，此時允許施加的大電壓稱為反向重復(fù)峰值電壓VRRM（Peak Repetitive Reverse Blocking Voltage），由于可控硅阻斷時的電阻不是無窮大，此時的電流稱之為反向重復(fù)峰值電流IRRM（Peak Repetitive Reverse Blocking Current）。這兩個值與之前介紹的IDRM、VDRM是一樣的，只不過IDRM、VDRM是在控制G極斷開、可控硅阻斷狀態(tài)下測量的，而IRRM、VRRM是在可控硅A、K極接反向電壓下測量的。如果在可控硅陽極A與陰極K間加上反向電壓時，開始可控硅處于反向阻斷狀態(tài)，只有很小的反向漏電流流過。當(dāng)反向電壓增大到某一數(shù)值時，反向漏電流急劇增大，這時，所對應(yīng)的電壓稱為反向不重復(fù)峰值電壓VRSM（Peak Non-Repetitive Surge Voltage）。

Therefore, this parameter is often labeled as the on state average current IT (RMS), which refers to the average of the power frequency sine half wave current (within a cycle) that the thyristor component can continuously pass through. At this time, the current flowing through the G and K poles is the gate current IG (Gate Current). This gate control current should not exceed the gate maximum peak current IGM (Forward Peak Gate Voltage). When VAK is the negative half cycle of the AC power supply, the thyristor should not exceed the gate maximum peak current IGM (Forward Peak Gate Voltage) The K poles are blocked by adding a reverse voltage, and the large voltage allowed to be applied at this time is called the Peak Repetitive Reverse Blocking Voltage (VRRM). Since the resistance when the thyristor is blocked is not infinite, the current at this time is called the Peak Repetitive Reverse Blocking Current (IRRM). These two values are the same as the previously introduced IDRM and VDRM, except that IDRM and VDRM are measured under the control of G pole disconnection and thyristor blocking state, while IRRM and VRRM are measured under the reverse voltage of thyristor A and K pole connection. If a reverse voltage is applied between the anode A and cathode K of the thyristor, the thyristor begins to be in a reverse blocking state, with only a small reverse leakage current flowing through. When the reverse voltage increases to a certain value, the reverse leakage current sharply increases, and the corresponding voltage is called the Peak Non Repetitive Surge Voltage (VRSM).
