Abstract: An electric drive system includes a power electronics module with a DC-DC converter and an inverter. The power electronics modules include a plurality of Silicon Carbide switches. Dynamic models are used to estimate the temperatures of the switch junctions and of the Direct Bond Copper substrate. The dynamic models rely on a coolant flowrate value from a coolant system. If the estimate of the substrate temperature differs substantially from a measured substrate temperature, a controller concludes that the coolant system is not delivering the stated flow rate of coolant and takes remedial action such as reducing motor torque to zero.
