Definition of the Solid State Circuit Breaker limits working with active clamp driver

The Solid State Circuit Breaker (SSCB) is conveniently used to substitute classical circuit breaker for the applications where the circuit breaker works with high mechanical stress (i.e. high vibrations, shock etc) and the dimension and weight must be reduced. Among the SSCB family, the snubberless SSCB have been recently introduced for particular application that differs from the classical SSCB because waste the load energy in the SSCB itself during the turn-off time. This is possible by using particular IGBT/MOSFET drivers with active clamp circuits. In this paper the authors find the limits of this class of SSCB circuits and define the key elements that act on the them.
