Abstract

A controller reduces power output of an inverter of an electric drive system while a sensed temperature associated with the inverter, a sensed current output of the inverter, and parameter values of a busbar of the inverter are indicative of a predicted temperature of the busbar being greater than a threshold to maintain busbar temperature lower than the threshold. The current output of the inverter may be outputted over the busbar. The parameter values are obtainable from a thermal model of the busbar. The thermal model may be derived from testing a test version of the inverter under different drive cycles in which for each a set of information is recorded including a sensed temperature of the test inverter, a sensed current output of the test inverter, and a sensed temperature of the busbar of the test inverter.
