【発明の名称】スイッチング装置
Document Type and Number:
Japanese Patent JP3384522
Kind Code:
B2
Abstract:
To turn on or off semiconductor switches based on the current-duration product of a current flowing through them, the device of the present invention detects an ambient temperature of the harness and, based on thus detected ambient temperature, corrects a detected current value to compare the current-duration product of thus corrected current value to the threshold data, so that if that product value equals or exceeds that threshold data value, the semiconductor switches are turned off, thus avoiding the affection due to the heat from the engines or the semiconductor switches to effectively prevent the harness from fuming.
