Title:
BIDIRECTIONAL DC CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2018/151489
Kind Code:
A1
Abstract:
The present invention relates to a bidirectional DC circuit breaker, which using a main inductor so as to rapidly reduce the amount of fault current, thereby reducing the amount of necessary LC resonance current, and reducing the amount of residual current flowing into a receiving unit or a transmitting unit. In addition, separate charging is unnecessary since a capacitor is charged by using a current in a normal current state and a reverse charging switch. A closed loop is formed such that a fault current flows into a receiving unit or a transmitting unit, thereby enabling secondary damage such as fire to be prevented.
