Open AccessThe purpose of this paper is the synthesis from the frequency domain standpoint of a controller for switching power converters with the aim to eliminate bifurcation and chaotic behavior. Firstly the paper analyzes the ...
A ripple-based design-oriented approach for predicting fast-scale instability in DC–DC switching power supplies Rodríguez Vilamitjana, Enric; El Aroudi, Abdelali; Guinjoan Gispert, Francisco; Alarcón Cot, Eduardo José (2011-12)
Restricted access - publisher's policyThis paper presents a design-oriented analytical approach for predicting fast-scale instability in power electronics converters under voltage-mode control strategy. This approach is based on the use of the ripple amplitude ...
Demonstration of ripple-based index for predicting fast-scale instability in switching power converters Rodríguez Vilamitjana, Enric; Alarcón Cot, Eduardo José; El Aroudi, Abdelali (2009-05)
Open AccessIn this paper a simplified model based on the exact discrete-time map of a buck switching power converter with proportional control, which captures all its dynamics, allows deriving a closed-form stability condition for ...
Design-oriented model for predicting and controlling fast-scale instabilities in switching converters.application to advanced power management integrated circuits Rodríguez Vilamitjana, Enric (Universitat Politècnica de Catalunya, 2011-02-28)
