“…Usually the averaged models of the converter power stage are used, representing relations between currents and voltages averaged over an elementary switching period. Standard methods of an averaged model derivation, namely state-space averaging and switch pair averaging are widely described in the literature, for example [1,2,[6][7][8][9]. The switch averaging approach is most commonly used and is described in many references as more convenient than state-space averaging [1, 2, 7 ,8].…”

Abstract. Large-signal and small-signal averaged models of basic switch-mode DC-DC power converters: BUCK (step-down) and BOOST (step-up) are presented. Models are derived with the separation of variables approach and have the form of equivalent circuits, suitable for a circuit simulation. Apart from equivalent circuits, small-signal transmittances of converters for CCM and DCM modes are discussed. Parasitic resistances of all components of converters are taken into account. A few examples of simulations and measurement results of selected converter characteristics are also presented. It is shown, that neglecting parasitic resistances (often met in works of other authors) may lead to serious errors in an averaged description of converters.

“…For more advanced control design, state variable model is usually a prerequisite. Various modeling approaches for switching power converters of complex topology have been proposed in the literature [15][16][17][18][19][20]. Most of them have been successful in terms of modeling the "local" behavior (i.e., small signal model) or analysis of the fundamental characteristics.…”

This chapter provides the reader with a control-centric modeling and analysis approach along with a nonlinear control design for a class of switching power converters. A comprehensive model combining the respective state variable models of the interval subsystems is established. Comparison with PSpice simulation justifies the credibility of the model. Based on this model, internal/BIBO stability can be studied for each interval subsystem. Moreover, controllability and observability can also be analyzed to help determine subsequent control configuration. The established model is further investigated for advanced control design, i.e., robust adaptive fuzzy control.

“…La solución DMPPT (Fig. 3) garantiza la operación de cada PV en su respectivo MPP, y por tanto extrae la máxima energía disponible del arreglo [17]. Pero, esta solución requiere una cantidad elevada de convertidores CC/CC, uno por cada PV del arreglo, así como de un número elevado de controladores MPPT, uno por cada PV del arreglo [18].…”

Este articulo presenta un modelo para sistemas de generación fotovoltaica orientado a evaluar el desempeño de algoritmos distribuidos de búsqueda del punto de máxima potencia. El modelo considera la conexión en serie de n conjuntos módulo-convertidor que pueden ser dimensionados dependiendo de la aplicación en particular. Dicho modelo está compuesto por un conjunto de ecuaciones que pueden ser implementadas en cualquier software de cálculo matemático o en un lenguaje de programación que soluciones este tipo de ecuaciones. El modelo incluye el comportamiento estático del módulo fotovoltaico a partir de una ecuación que estima su relación voltaje-corriente, además, incluye el modelo del convertidor elevador de potencia con pérdidas en el inductor, esto con el fin de aproximar el modelo general a una solución realística de la aplicación. El modelo final es validado mediante simulaciones y comparado con una implementación del mismo en un software de simulación electrónica tradicional.
