Abstract
Abstmct--This paper describes a new algorithm for &dation of power electronic systems. Piece*-linear approximation is used to model nonlinear components, including switching devices, nonlinear reactive components, and nonlinear control circuitry. A repmentation of PWL elements is c~nstructed such that a constaet system matrix is obtained, regardless of the state8 of PWL dements. An &dent method for state determination is proposed, which is capable of resolving difllculties caused by discontinuous characteristics of PWL elements. The resulting simulation algorithm is quite general, requires no prior knowl- edge of the circuit operation, is void of convergence problems, and yields relatively short simulation times on desktop PC machines.Keywords
