Globally, a lot of research is being conducted on LVDC(Low Voltage Direct Current) technology due to the increase in renewable energy, microgrids, and various digital loads. Since the DC circuit breaker is essential in the LVDC systems, the importance of DC circuit breaker is also highlighted. Most LVDC systems are composed of multi-port systems. If the existing DC circuit breakers are used in this multi-port system, it is not cost-effective because the number of elements increases significantly as the number of ports increases. Therefore, a solution that can use DC circuit breakers more efficiently is needed in multi-port systems. In this paper, we propose a multi-port DC solid-state circuit breaker for LVDC multi-port systems. The proposed multi-port circuit breaker can perform blocking operations on all ports through one blocking section. In other words, even if the number of ports increases, only the main thyristor section and the auxiliary thyristor section need to be added, making it easy to expand the ports. In addition, there is an advantage that the commutation capacitor for the circuit breaker to perform a re-blocking operation can be recharged very quickly. The proposed multi-port circuit breaker is verified through experiment.
