DEVICE, METHOD, SYSTEM (UTILIZING OF OVERVOLTAGE AND OVERCURRENT COMPENSATION FOR EXPANDING EFFECTIVE OPERATION RANGE OF ELECTRONIC DEVICE)

摘要

PROBLEM TO BE SOLVED: To provide a system and method for controlling temperature of a high power device.;SOLUTION: By a heat control and temperature monitoring system (HCTMS), a jointing temperature of components is monitored using a temperature sensor (403), and an applied power is increased so that a self heating characteristics is enhanced by a zero input leakage current specific to the component (404). Preheating of a device is accelerated so that attaining of the component to a functional temperature range is accelerated (410). The system then applies an overall system power to execute an initializing sequence (411). Even after the component comes into an operation state, the temperature of the component is kept at the operation temperature range higher than the lowest operation threshold by continuous self heating, continuous increase of applied DC voltage, or by both of them as required (412).;COPYRIGHT: (C)2009,JPO&INPIT
