In this paper we propose a novel model of the ripple produced in different contexts involving switching power electronics. The novelty of this model is that the nonsmooth waveform characterizing the ripple is captured by a suitable hybrid dynamics performing state jumps at the switching instants. In addition to showing that this model is effective at representing the ripple waveform, we propose two hybrid schemes ensuring asymptotic observation of the ripple waveform, one of them using knowledge of the switching instants and a second one without knowledge of the switching instants. Simulation results illustrate the effectiveness of the proposed hybrid observation laws.
