Title:
ＤＣ／ＤＣコンバータの制御装置
Document Type and Number:
Japanese Patent JP6869343
Kind Code:
B2
Abstract:
With respect to a failure in voltage sensors each for detecting a high-voltage-side voltage in a DC/DC converter, it is so arranged that a circuit failure of the DC/DC converter is prevented, and that the DC/DC converter is continuingly controlled. Two voltage sensors are included therein each for detecting a high-voltage-side voltage, so that, even when a first voltage sensor for detecting a high-voltage-side voltage on one side fails to work properly, a control device turns on a second switching device, and detects a voltage by a second voltage sensor for detecting the high-voltage-side voltage on the other side, whereby a failure of the voltage sensor for detecting the high-voltage-side voltage is detected.
