Abstract

To improve the simulation efficiency of switched circuits, it is advantageous to model their switching devices as short and open circuits. The disadvantage is that such models may cause inconsistent initial conditions (IIC), and Dirac impulses may appear. Conventional simulators do not handle such situations correctly. This paper introduces a new algorithm for analyzing circuits with IIC by a mixed numerical-symbolic method. The method detects the order of the Dirac impulse and also finds the correct initial conditions after switching. It is applicable to nonlinear circuits.
