Beschreibung
Zusammenfassung:	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. 描述了种电连接至电动机的逆变器。种用于控制逆变器中的切换的方法包括确定电动机的扭矩输出并且确定与逆变器冷却回路相关的温度。基于电动机的扭矩输出和与逆变器冷却回路相关的温度来选择用于控制逆变器的优选逆变器开关控制模式。
