title = "Enhanced Model-Based Design and Optimization Method for Coupled Z-Source Circuit Breakers",
abstract = "DC microgrid has been applied in various fields due to its high efficiency. The short-circuit fault protection of circuit breakers is significant to the development of the DC microgrid. The existing modeling method for the Q-Z-Source circuit breaker is not accurate enough for guiding a model-based design. In this paper, an enhanced modeling method for the Q-Z-Source circuit breaker is proposed to improve the accuracy of the modeling. The operational principle and circuit analysis are elaborated with mathematical models, which can provide detailed parametric design methods in the short-circuit fault transient. Meanwhile, an optimization method for the total inductance of the circuit breaker implemented by MATLAB is proposed to reduce the weight and volume of the circuit breaker. Finally, Saber-based simulation results are utilized to verify the effectiveness of the modeling method and the parameters design.",
