None of the existing network reduction tools preserve passivityfor RLC networks. The loss of passivity can be a serious problembecause simulations of the reduced networks may encounter"time step too small" errors. This paper presents a set oftransformations called "Split Congruence Transformations"(SCT's) which can be used to accurately reduce a RLC networkwhile preserving passivity.
