PROBLEM TO BE SOLVED: To provide a method and system for efficiently extending the operating temperature range of high power components within a system/device.;SOLUTION: An embedded monitor measures local temperatures such as junction temperatures of components. When the measured temperature is less than the lowest operational temperature threshold of the component, temperature control logic initiates pre-heating to raise the temperature of the component to an operational level, utilizing a heating source. The component (or device) is made operational only when the temperature is at or above the operational level. The temperature control logic maintains the operational temperature of the component using the high power dissipated by components within the operating system/device as a self heating source. If self heating is unable to maintain the operational temperature, the heating source is utilized to assist in maintaining the operational temperature of the component, and thereby extends the useable operational temperature range of the system in which the components are employed.;COPYRIGHT: (C)2013,JPO&INPIT
