Review and Analysis of Voltage Clamping Circuits With Low Overvoltage Ratios for DC Circuit Breakers
Publikováno v:
IEEE Open Journal of the Industrial Electronics Society, Vol 5, Pp 651-662 (2024)
Voltage clamping circuits are critical components in most direct-current circuit breakers (dcCBs) to achieve ultrafast dc fault interruptions and an extended lifetime. A key performance index of voltage clamping circuits is the overvoltage ratio, whi
