Method for regulating temperature of transistor-based component

摘要

A method of regulating temperature of a transistor-based component of a power system is disclosed. The method may include operating the power system to supply electric power to the transistor-based component and converting the electric power from direct current to alternating current, or alternating current to direct current, using the transistor-based component, thereby creating heat in the transistor-based component. The method may include outputting the electric power from the transistor-based component and supplying the electric power to an electrically-powered component to perform an output operation. The method may include controlling, during a predetermined system operating condition, one or more operations of a component associated with the power system to actively generate heat to thereby maintain the temperature of the transistor-based component higher than from the conversion of electric power that is performed to produce the electric power used to perform the output operation during the predetermined system operating condition.

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.
