Recent advances concerning the problem of finding Internally Controlled Switching Instants (ICSI) in Switched RLC (SRLC) Circuits by means of
Interval Analysis
(IA) are reported in this paper. A method is proposed which is based on the joined application of real analysis and IA, using Krawczyk's operator to detect safe starting regions for Newton's formula. Further improvements concerning intervals width minimization have been realized, which ensure fast convergence and high reliability. Some examples of applications are presented, concerning the
numerical analysis
of switching converters, for which the most significant computational aspects are discussed

], we are able to bound reliably the intervals of D wherein jf(D)j is smaller than the saturation voltage of the OpAmp, which are the same regions where we must seek D0. These intervals are tightly bounded and are safestarting regions for the application of classical real arithmetic rootsearch methods, which can be ...
