Steady-state analysis of soft-switching converters is treated in this paper. Finding the steady-state solution of soft-switching converters by means of start-up transient simulation may involve onerous computations and convergence failure because of the mix of fast and slow natural frequencies determined respectively by the presence of soft-switching Lr-Cr cells elements and bulky L-C filter elements. The numerical method proposed in this paper shows high reliability and fast convergence, thanks to the adoption of an Interval Analysis-based technique for the detection of commutations and of a Compensation Theorem-based technique for the analysis of commutations. An example, discussed in depth, of steady-state analysis of a dc-dc converter is presented to highlight the good performances of the simulation algorithm.

Abstract
Steady-state analysis of soft-switching converters is treated in this paper. Finding the steady-state solution of soft-switching converters by means of start-up transient simulation may involve onerous computations and convergence failure because of the mix of fast and slow natural frequencies determined respectively by the presence of soft-switching Lr-Cr cells elements and bulky L-C filter elements. The numerical method proposed in this paper shows high reliability and fast convergence, thanks to the adoption of an Interval Analysis-based technique for the detection of commutations and of a Compensation Theorem-based technique for the analysis of commutations. An example, discussed in depth, of steady-state analysis of a dc-dc converter is presented to highlight the good performances of the simulation algorithm.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
