After the UV light is turned off, the rate of on-state current decay more slowly than off-state current due to the effect of gate bias voltage. 2.
紫外光照移除后,栅极偏压的作用使得开态电流衰减比关态电流慢许多。
An ideal power device is designed to support a very high voltage in the off-state, possess a very small voltage drop in the on-state, support a very high current density, and be capable of switching at a very high speed.
一个理想的功率器件,希望其在关断时具有非常高的耐压能力,在通态时具有较低的正向压降;不仅能够承受非常大的电流密度,还具有较高的开关速度。
