Fundamentos de los ordenadores. V.2: Elementos de metateoría

Este libro ha sido escrito con el propósito de servir de texto a los estudiantes de la asignatura FUNDAMENTOS DE ORDENADORES en tercer curso del Plan de Estudios llamado "1.964 modificado" de la Escuela Técnica Superior de Ingenieros de Telecomunicación de Madrid, curso que hizo su debut en el período académico 1.977-78. De conformidad con este propósito se ha suprimido toda tendencia al lucimiento o a la erudición en aras de un mejor rendimiento didáctico de los conceptos básicos

Accurate Analysis of Subharmonic Oscillations of V^2 and V^2Ic Controls Applied to Buck Converter

V2Ic control provides very fast dynamic performance to the Buck converter both under load steps and under voltage reference steps. However, the design of this control is complex since it is prone to subharmonic oscillations and several parameters affect the stability of the system. This paper derives and validates a very accurate modeling and stability analysis of a closed-loop V2Ic control using the Floquet theory. This allows the derivation of sensitivity analysis to design a robust converter. The proposed methodology is validated on a 5-MHz Buck converter. The work is also extended to V2 control using the same methodology, showing high accuracy and robustness. The paper also demonstrates, on the V2 control, that even a low bandwidth-linear controller can affect the stability of a ripple-based control.
