LIFE OF A SEMICONDUCTOR BY REDUCING TEMPERATURE CHANGES THEREIN VIA SWITCHING FREQUENCY

摘要

Provided is system including a temperature regulator including at least on regulation component in communication with a semiconductor within a converter, and a peak detector in communication with the semiconductor within the converter configured to identify a maximum temperature of each semiconductor. Also provided is a method for regulating temperature change of semiconductor components including measuring a semiconductor temperature, determining a reference temperature when the semiconductor is energized, summing the first semiconductor temperature and the reference temperature to generate a first temperature sum, comparing the first temperature sum to a coolant temperature to generate a first temperature difference. The method also circulates a fluid configured within the system such that the first temperature difference is adjusted.
