This device is parasitic latch up free, and exhibits the characteristic of output current decrease, instead of current saturation or increase at higher anode voltage. 这种器件无寄生闩锁效应,并在较高阳极电压下展现出电流下降而不是饱和或上升的特性。
In the constant torque range, this makes torque output capacity reduction and the terminal voltage of motor can not follow the supplied voltage in practical. In the constant power range, this makes reduction of performance caused by the saturation of voltage controller. 在恒转矩区,转矩输出能力降低和机端电压不能准确跟踪给定电压;在恒功率区,造成电压控制器饱和,控制性能降低。
