Title:
DIRECT CURRENT CIRCUIT, MOVING BODY AND POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/221561
Kind Code:
A1
Abstract:
[Problem] To provide a direct current circuit capable of, when a semiconductor is used for suppressing an arc discharge, securing safety even if a short circuit occurs when the semiconductor has deteriorated.
[Solution] Provided is the direct current circuit comprising: a first current path and a second current path provided in parallel on a path where a direct current flows; a circuit using a first switch provided on the first current path to allow a pulsed current of a predetermined duration to flow when the direct current in the second current path is shut-off; and a second switch provided at a stage preceding the first switch, and of which the connection is maintained by a pulling force from a fuse. When the fuse melts, the second switch adopts an open state. The fuse has such a rating as not to melt at a rated energization current during rated energization of the circuit.
