This paper proposes Small Signal Analysis of IGBT
based on SSCB for the low voltage level by using IGBTs. According to the
conventional circuit breaker, the SSCB was developed. The rapid operation and arcless
are proposed on the protection devices that can operate under malfunction. The
SSCB based on IGBT can be modeled on small signal averaging model for searching
the turn-on and turn off performance. The gate drive signal of IGBT is
generated by using malfunction detection technique. The voltage and current
sources of proposed system can be properly controlled under the proposed
condition. The simulated results found that SSCB can be operated under several
testing condition and voltage and current signal can be express as reality
behavior at turn-on and turn-off condition according to internal parasitic
parameter of IGBTs and loads. Therefore, SSCB can be normally used for
controlling the voltage and current instead of a circuit in the system.
