Steady-state time-domain simulation of power converters using a differentiation matrix

A technique for simulating the steady-state response of power converters has been proposed in this paper. The technique is based on the definition of a differentiation matrix. It converts differential into algebraic equations and provides the signals in the time domain. This allows obtain directly the steady-state responses of power converters without to generate all the previous transients points. The Differentiation matrix is still simple to apply and is rapidly convergent. The accuracy of the technique has been established and the responses of three circuits with soft-switching and feedback control has been presented
