Parallel resonance type fault current limiting circuit breaker

High Voltage, Volume 5, Issue 1, Page 76-82, February 2020., 2020
The main goal of this study is introducing a novel fault current limiter based on parallel resonance structure (PRFCL) for high voltage application. During normal mode, the PRFCL reactor is short‐circuited via a rectifier bridge DC output voltage and LC resonance tank shows negligible impedance in the line. During a fault, the rectifier bridge switches
