Switchings of electronic devices can be classified as external if forced by directly manipulable control variables, and internal if determined by state dependent conditions. The presence of internal switchings makes it difficult to know a priori the sequence of modes and also open loop steady-state behaviours are difficult to obtain. In this chapter, it is shown how linear complementarity systems can be used to model the behaviour of a wide class of power converters. The complementarity framework is suitable for modelling piecewise-linear characteristics of diodes and controlled electronic switches. The combination of such models with a state-space representation of the circuit allows obtaining a model of the power converter which is valid for any operating mode. The discretization of this model allows the formulation of a static complementarity problem whose solution provides the steady-state oscillation of the converter, either in open or closed-loop. Throughout the chapter, the usefulness of the complementarity formalism for the analysis of power converters is shown by considering three challenging examples: a DC–DC voltage-mode pulse-width modulated boost converter, a resonant converter and a switched capacitors converter are used as examples.

A procedure for representing the closed loop system in complementarity form, based on resistors-diode-sources equivalent circuits of the piecewise linear characteristic is presented. Conditions for the existence of discretetime periodic solutions in terms of solvability of a suitable static linear complementarity problem are obtained. Numerical results for a chaotic circuit show that the proposed approach can be also used to predict periodic solutions of continuoustime systems in Lur´e form provided that consistency of the discretization is assumed.

At a certain level of abstraction, switched models are able to capture some interesting properties of the converters behaviour while ignoring irrelevant details. Switched models of power converter have rich dynamical behaviour, so the formal analysis of these systems could be difficult. An effective widely used approach to circumvent some of these difficulties is the averaging technique. In this chapter, the formal approaches proposed in the literature to deal with the averaging of switched systems are presented. The general averaging over a moving time window, the dithering and the dynamic phasor models are recast and compared by considering models for various type of power converters as a common framework.
