Abstract
An inverter electrically connected to an electric machine is described. A method for controlling switching in the inverter includes determining a torque output of the electric machine and determining a temperature related to an inverter cooling circuit. A preferred inverter switch control mode for controlling the inverter is selected based upon the torque output of the electric machine and the temperature related to the inverter cooling circuit.
