Abstract
An arc detection device includes: a low-impedance circuit connected between a node on wiring connecting the positive electrode of a DC/DC converter and a plurality of DC/DC converters, extending from the positive electrode of the DC/DC converter, and branching toward the plurality of DC/DC converters and a node on wiring connecting the negative electrode of the DC/DC converter and the plurality of DC/DC converters, extending from the negative electrode of the DC/DC converter, and branching toward the plurality of DC/DC converters; an electric current detector that detects an electric current flowing through the low-impedance circuit; and an arc determiner that determines, on the basis of the electric current detected by the electric current detector whether an electric arc has occurred.
