Title:
TEMPERATURE DETECTION DEVICE AND POWER CONVERSION DEVICE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2018/190063
Kind Code:
A1
Abstract:
The present invention further enhances the accuracy of the detection of the temperature of an object and makes more flexible temperature detection possible. This temperature detection device outputs, on the basis of a temperature signal input from a temperature sensor, an electrical signal corresponding to the temperature signal, and uses a prescribed temperature threshold to change a temperature slope that is the amount of change in output corresponding to the amount of change in the temperature signal. This temperature detection device 1 is provided with an output calculation unit 2 for calculating outputs in relation to the temperature signal for two or more different temperature slopes and an output selection unit (multiplexer) 3 for selecting one of the two or more outputs output from the output calculation unit on the basis of the temperature threshold.
