    摘要: Permanent magnet alternating current (PMAC) motor systems and methods for starting or restarting PMAC motor system sensorless control algorithms are provided. One system includes a PMAC motor including a rotor, an inverter, and a controller. The controller includes control logic, start/restart logic, drive logic, current detect logic, and estimation logic configured to estimate a position of the rotor, a speed of the PMAC motor, or both based on current detected in each phase of the inverter. A start/restart method includes determining to start/restart the sensorless control algorithm and modifying the inverter voltage in response to the determined start/restart. The method also includes detecting current in each inverter phase after the inverter voltage is modified and estimating a rotor position, a PMAC motor speed, or both based on the current detected in each inverter phase after the inverter voltage is modified. Another controller includes means for performing the above start/restart method.

    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.
