Abstract: A cooling system is thermally coupled to a power electronic system and configured to carry heat away from the power electronic system using a cooling agent. A system controller is configured to receive information concerning a sensed temperature of a semiconductor switch and a temperature of the cooling agent (coolant). The system controller is further configured to adjust a power of the power electronic system by controlling the switching operation of the semiconductor switch. When the temperature of the coolant is below a threshold temperature, then the controller adjusts the power of the power electronic system to a target value greater than the rated maximum power based on the sensed temperature of the semiconductor switch and the temperature of the cooling agent.
