摘要： A method for providing thermal protection for forced air cooled power electronic semiconductors without direct measurement of semiconductor temperature, the semiconductors being mounted on a heat sink over which cooling air is blown includes the steps of computing the cooling air mass flow rate, creating an electronic model of the semiconductor/heat sink combination and estimating the semiconductor junction temperature from the mass flow rate and model. The cooling mass flow rate is determined by measuring the temperature of the cooling air prior to passage over the heat sink, measuring atmospheric pressure of the cooling air, determining the volumetric air flow rate of the cooling air and computing, from the cooling air temperature, pressure and volumetric flow rate, the cooling air mass flow rate. Power dissipation in the semiconductors is then computed and heat sink and semiconductor temperatures are estimated from power dissipation and cooling air mass flow rate. Semiconductor power dissipation is limited so as to restrict semiconductor temperature to a safe operating value.

摘要： A method for predicting mechanical failure of a traction motor in a vehicle includes monitoring first characteristics of an electrical signal supplied to a traction motor of a vehicle during a first detection window. The first characteristics represent a first motor electrical signature for the traction motor. The method also includes deriving one or more signature values from a first mathematical model of the first motor electrical signature and predicting a mechanical failure of the traction motor based on the one or more signature values.
