In a drive system of power transistor inverter-motor, not only can it be used in fine control of motor current waveform, phase, amplitude and frequency, but can also be used to sense, fault current.

在大功率晶体管逆变器——电动机驱动系统中，它不但可用来对电动机电流的波形、相位、幅值和频率进行精细控制，而且能快速地检测出故障电流。

Every hybrid motor needs an inverter, and the key component inside inverters is the integrated gate bipolar transistor, or IGBT.
