Abstract:
1. A method of regulating a temperature of a transistor-based component of a power system, the method comprising: operating the power system to supply electric power to the transistor-based component; converting the electric power from direct current to alternating current, or alternating current to direct current, using the transistor-based component, thereby creating a first heat in the transistor-based component as a by-product of the conversion; outputting the converted electric power from the transistor-based component and supplying the converted electric power to an electrically-powered component; operating the electrically-powered component to perform an output operation; controlling, during a predetermined system operating condition, one or more operations of a component associated with the power system to actively generate a second heat, to which the transistor-based component is subjected, to prevent the temperature of the transistor-based component from dropping or to limit a temperature drop of the transistor-based component, thereby reducing temperature variation experienced by the transistor-based component; wherein the power system includes a mobile machine; and wherein the predetermined system operating condition includes idling of the mobile machine, and wherein idling includes any operating mode of the mobile machine during which an engine and/or a generator of the mobile machine is operating but there is no electrical power or substantially no electrical power being consumed by the engine and/or generator.
