INTELLIGENT POWER MODULE AND METHOD FOR EVALUATING INTELLIGENT POWER MODULE

摘要

PROBLEM TO BE SOLVED: To provide an intelligent power module capable of detecting a change in the characteristics of a semiconductor chip for power and a method for evaluating the intelligent power module.SOLUTION: An intelligent power module 1 includes: a chip temperature detection circuit 8 for detecting a chip temperature as the temperature of an IGBT chip 10; a case temperature detection circuit 9 for detecting a case temperature as the temperature of a case enclosing the intelligent power module 1; and a memory circuit 6 for recording the chip temperature detected by the chip temperature detection circuit 8 and the case temperature detected by the case temperature detection circuit 9. The memory circuit 6 records the chip temperature and the case temperature at a first timing at which the IGBT chip 10 is driven and the chip temperature and the case temperature at a second timing at which the IGBT chip 10 is driven after the first timing.SELECTED DRAWING: Figure 1
