Title:
IN-VEHICLE BREAKING CURRENT SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/162200
Kind Code:
A1
Abstract:
An in-vehicle breaking current supply device (10) comprises a transformer (20) having a first winding (21) and a second winding (22), a drive unit (12), and a capacitor (28). The drive unit (12) switches between an allowable state in which the energization of the first winding (21) is allowed and a cancellation state in which the allowable state is canceled. The capacitor (28) is electrically connected to an intermediate conductive path between the second winding (22) and a circuit breaker (6) and can receive power from the second winding (22). A charging current is supplied to the capacitor (28) from the second winding (22) side in response to the drive unit (12) alternately repeating switching between the allowable state and the cancellation state. When a switch (30) is turned on, the capacitor (28) is discharged, and a drive current flows to a current input unit (7).
