solid-state circuit breaker, DC-DC converter, protection
To solve the problems of the circuit breakers based on thyristors connected with DC-DC converters in the DC grid, such as the failure of breakers to be turned off and output ripples of converters becoming larger because of the interaction between them, an integrated design is proposed. When this converter works in steady state, the ripple is tiny. When a fault occurs, it can isolate the fault effectively. Finally, two groups of contrast experiments are set to verify its performance.
