Design and Implementation of an Auto-Oriented Bidirectional ZCS Hybrid Circuit Breaker

To protect power systems from severe short circuit faults, the zero-current switching (ZCS) technique is widely accepted due to its fast interruption speed. However, the traditional ZCS technique is more complicated in bidirectional switching, which limits its wide application, especially in AC powe...
