【摘要】 通过合封的方式将碳化硅（SiC）光触发晶闸管与紫外（Ultraviolet, UV）发光二极管（Light??emitting diode,LED）进行集成，试制了SiC光触发晶闸管与UV LED的合封模块样件，并对其特性进行了测试与分析。结果显示，合封样件的阳极阻断电压大于8 500 V，阳极正向开启电压为2.8 V，栅极正向开启电压为3 V。在正向电流为20 A时，合封样件的阳极通态压降仅3.6 V。在2 000 V母线电压下，合封模块可通过栅控开通，阳极开通时间为8.5 ns，对应的dv/dt（器件电压随时间的变化率）与di/dt（器件电流随时间的变化率）分别为188 kV/μs与2.68 kA/μs。更多还原

【Abstract】 In this work, silicon carbide(SiC) light triggered thyristor and ultraviolet(UV) light??emitting diode(LED) were integrated by means of sealing. The sealing module samples of SiC light triggered thyristor and UV LED were trial??produced, and their characteristics were tested and an??alyzed. The results show that the anode blocking voltage of the sealed sample is greater than 8 500 V, the anode forward opening voltage is 2.8 V, and the gate forward opening voltage is 3 V. When the forward current is 20 A, the anode on??state voltage drop of the sealed sample is only 3.6 V. Under the 2 000 V bus voltage, the sealing module can be turned on by gate control. The anode turn??on time is 8.5 ns, and the corresponding dv/dt(the time derivative of the voltage across the device) and di/dt(the time derivative of the device current) are 188 kV/μs and 2.68 kA/μs, respectively.更多还原
