【Abstract】 Based on the study of the working principle of hybrid type dc high temperature superconducting fault current limiter and dc S/N transition rectifier bridge type high temperature superconducting fault current limiter(HTSCFCL),the concept of a hybrid fault current limiter has been introduced.A new single-phase hybrid type dc high temperature superconducting fault current limiter has been proposed,which is based on a new fast acting IGBT to control the protection resistor within 100μs after fault detection.MATLAB simulation has proved that the new design method is an effective approach for the accurate design parameters and its promise limiting-current results.更多还原
