POWER SWITCH PROTECTION SYSTEM AND METHOD

An electric vehicle includes a direct current (DC) power source with a DC electric power output. An inverter is coupled to receive the DC electric power output of the DC power source, and the inverterhas an alternating current (AC) electric power output. An electric motor is coupled to receive the AC electric power output. The electric motor has a driving torque output that is coupled to drive atleast one wheel of the vehicle. The inverter further includes a power semiconductor switch, such as an insulated-gate bipolar transistor (IGBT). A protection circuit is coupled to the power semiconductor switch, and the protection circuit has an adjustable protection detection level circuit. 电动车辆包括具有直流(DC)电力输出的DC电源。逆变器被耦合以接收DC电源的DC电力输出，并且逆变器具有交流(AC)电力输出。电动机被耦合以接收AC电力输出。电动机具有驱动转矩输出，其被耦合以驱动车辆的至少个车轮。逆变器进步包括功率半导体开关，诸如绝缘栅双极型晶体管(IGBT)。保护电路耦合到功率半导体开关，并且保护电路具有可调保护检测电平电路。
