Abstract
An electric drive system includes an inverter and a variable voltage converter. An inductor associated with the variable voltage converter is subject to temperature limits. Dynamic models are used to estimate the temperature of the inductor. Inputs to these dynamics models include DC current, DC voltage, Battery Voltage, oil pump speed, motor speed, and sump temperature. Empirical constants in the models are set based on vehicle testing.
