A Novel Helical Superconducting Fault Current Limiter for Electric Propulsion Aircraft
IEEE Transactions on Transportation Electrification, 2021 It is crucial to achieve a high safety and reliability standard in future electric propulsion aircraft (EPA). Due to low short-circuit impedance and high rate of fault current rise in EPA systems, the superconducting fault current limiter (SFCL) plays a ...
