Abstract

An in-vehicle interrupting current supply device includes: a transformer that includes a first winding portion and a second winding portion; a driving unit; and a capacitor. The driving unit performs switching between a permission state in which current conduction to the first winding portion is permitted and a cancellation state in which the permission state is cancelled. The capacitor is electrically connected to an intermediate conductive path between the second winding portion and an interrupter, and can receive electric power from the second winding portion. In response to the driving unit repeating alternate switching between the permission state and the cancellation state, a charge current is supplied from the second winding portion side to the capacitor. The capacitor is discharged in response to a switch performing an ON operation, and a driving current flows into a current input portion.
