发明名称 TEMPERATURE DETECTING APPARATUS AND COMPUTER PROGRAM THEREFOR
摘要 A temperature detecting apparatus detects a temperature of a detection target having a switch element. The temperature detecting apparatus includes a current detecting unit and a temperature estimating unit. The current detecting unit detects an output current from the detection target changing depending on an on/off operation of the switch element. The temperature estimating unit, on the basis of a current value detected by the current detecting unit, calculates a conduction loss of the switch element and a switching loss of the switch element to estimate the temperature of the detection target on the basis of the calculated conduction loss and the calculated switching loss.

主权项 1. A temperature detecting apparatus that detects a temperature of a detection target having a switch element, comprising: a current detecting unit that detects an output current from the detection target changing depending on an on/off operation of the switch element; and a temperature estimating unit that obtains a conduction loss of the switch element and a switching loss of the switch element on the basis of the current value detected by the current detecting unit and estimates the temperature of the detection target on the basis of the obtained conduction loss and the obtained switching loss.
