Title:
CONTROL DEVICE FOR DC-DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2018/225235
Kind Code:
A1
Abstract:
The present invention makes it possible to continuously control a DC-DC converter by eliminating a circuit failure of the DC-DC converter with respect to a failure of a voltage sensor for detecting a high voltage-side voltage in the DC-DC converter. The present invention has two voltage sensors (201a, 201b) for detecting the high voltage-side voltage, and even if a first voltage sensor (201a) for detecting the high voltage-side voltage fails, a control device (300) turns on a second switching element (104), detects the voltage by means of the other second voltage sensor (201b) for detecting the high voltage-side voltage, and detects the failure of the voltage sensor for detecting the high voltage-side voltage.
