Abstract :
In this paper, demand for Solid State DC Circuit Breaker for Super Uninterruptible Power Supply (UPS) is analyzed firstly. Design of the Solid State DC Circuit Breaker is investigated. Then the optimized structure with RCD+MOV is designed to reduce the voltage stress of the power device. Furthermore, the detection of short-circuit current is provided. Finally, a prototype is built to verify the design.
