  • Publication number: 20250233400
    Abstract: An in-vehicle interrupting current supply device includes a transformer including a first winding portion and a second winding portion, a switching unit, a capacitor, a discharge circuit, and an inhibiting unit. The switching unit switches between an allowance state in which current conduction to the first winding portion is allowed and a cancellation state in which the allowance state is cancelled. The capacitor is electrically connected to an intermediate conductive path between the second winding portion and the breaker and can receive electric power from the second winding portion. The discharge circuit discharges the capacitor through a path different from the breaker. The capacitor is discharged through the path in response to the inhibiting unit switching to a permission state.
