Recently, the use of large-capacity DC distribution facilities has increased owing to renewable energy facilities such as solar power, fuel cells, and energy storage systems (ESS). Furthermore, electrical applications such as electric vehicles and electric propulsion ships are increasing. For those reasons, the DC current-blocking technology which can protect such facilities and devices from electrical shocks has become an important issue. Research on various types of DC circuit breakers such as the Z-Source structure has been actively studied. For example, to reduce components of the bidirectional DC circuit breaker, the coupled-inductor and thyristor (SCR) based on the Z-Source structure was previously proposed. However, the existing DC circuit breakers have problems such as control complexity and reliability. Therefore, in this paper, to improve the control reliability, a novel topology of a DC circuit breaker was proposed. The concepts and design methods were presented in this paper. To verify the proposed DC circuit breaker, experiments of the fault instant were implemented through a scaled-down test of a rated ±10 A-class prototype.
