PREDICTION OF TRANSISTOR TEMPERATURE IN AN INVERTER POWER MODULE OF A VEHICLE, AND RELATED OPERATING METHODS |
摘要 |
A power module system for a vehicle includes a circuit board, a power transistor mounted to the circuit board, and a temperature sensor mounted to the circuit board in a sensing location remote from the power transistor. The temperature sensor is configured to measure a real-time temperature at the sensing location. The system also includes a processor coupled to the temperature sensor to generate a predicted real-time silicon temperature for the power transistor from the measured real-time temperature at the sensing location. The predicted real-time silicon temperature is generated using a selected calibration curve that corresponds to a current operating state of the vehicle. |
