Diseño e implementación del control para un convertidor SEPIC MLEVEL

Abstract

The different studies aimed at improve the diverse DC - DC conversion topologies towards obtaining higher levels of voltage gain, have allowed the development of new additions to the typical conversion structures called multiplier or multilevel additions. Its use allows high voltage gains, without extreme duty cycles or cascading, this also offer a variable structure in which more output levels can be added without modifying the original structure of the conversion system. However, within the framework of the development of these studies, no research has been carried out on the control systems applied to these multiplier topologies. For this reason, this work aims to develop a robust control methodology applicable to a non-linear DC-DC converter such as the second order SEPIC multiplier, and will also make comparisons with linear control methodologies through a linearization of the system, in order to establish the differences present in each of them. Thus, once the control schemes have been developed, they will be implemented in a hardware prototype, where the simulated and implemented results will be included to verify their behavior
