Design and Development of Solid-state DC Circuit Breaker
- Developed a fast, low-loss solid-state DC circuit breaker with quick reclosing and rebreaking capabilities.
- Achieves low conduction loss and fast fault interruption using solid-state components.
- Operating modes and breaker characteristics are validated through detailed Simulink/MATLAB simulations.
- Hardware implementation of the circuit breaker has been successfully carried out.
- The breaker not only interrupts fault current but also recharges the commutation capacitor to enable rebreaking.
- Demonstrates rebreaking capability not available in existing DC circuit breakers.
