| Zusammenfassung: | An arc detection circuit includes: a current detector that detects a current supplied from a power supply apparatus via a transmission path; a voltage detector that detects a voltage applied to the transmission path; and an arc determination unit configured to determine whether an arc has occurred in the transmission path based on the voltage, when one or more particular frequency components of the current exceed a first threshold. |
