Summary:This article aims to study and comparison of nonlinear control techniques applied to static power converters type: buck, boost, buck-boost and flyback. Although they are basic building blocks in electronics, these converters have attracted growing interest in the power electronics and control areas. This is due to the diversity of applications including since household appliances to sophisticated electrical systems. Greater emphasis is given to the boost converter because it is the only converter analyzed with power factor correction (PFC), since it is the most suitable for this specific application. The other systems are analyzed as control voltage regulators (DC-DC) in which the input voltage comes up to a constant value. Due to a vast new field for nonlinear controls of converters, because they offer a more natural response and, especially, make electronic systems more efficient, nonlinear control algorithms are obtained and implemented: state feed-back linearization (SFL), passivity based control (PBC) and interconnection and damping assignment passivity-based control (IDA-PBC). Taking into account that many control laws require validation, this work employs high level programming with Malab / DSP integration using Hardware in The Loop (HIL) Simulation. This methodology facilitates the testing and collection of results and reduces the development cycle of the project.
