The aim of this study is to present a very simple, intuitive and feasible tool: the D-transform between converters. This new method proposes to find a control equation of any pre-defined control law from one converter to another power converter. The

The power produced in a photovoltaic (PV) system is highly dependent on meteorological conditions and the features of the connected load. Therefore, maximum power point tracking (MPPT) methods are crucial to optimize the power delivered. An MPPT meth

Partial shading is a problem that affects solar systems not only in their efficiency, but also in its lifetime. As a solution, integrated converters enable mismatched modules to deliver their maximum power. Voltage Equalizers are a type of partial po

This paper presents the design and implementation of a digital control strategy for a Buck converter, used as a solar charger of valve-regulated lead acid (VRLA) batteries. The control system consists of two fuzzy logic controllers (FLCs), which adju

In this paper, we propose adaptive nonlinear controllers for the Single-Ended Primary Inductance Converter (SEPIC). We also consider four distinct situations: AC-DC, DC-DC, Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM). A c

Partial shading has shown to be a common efficiency issue for photovoltaic arrays installations, whether for islanded or grid-tied systems. Current diverter appears as reasonable solution, but with the increasing of string order, the currents deviate

Neste artigo é discutido o uso da técnica de controle baseado em passividade aplicada a conversores estáticos do tipo abaixador de tensão (buck) e elevadores de tensão (boost) operando como corretores ativos de fator de potência (CFP). É propo

In this paper a flux observer and torque estimator for the induction motor is presented which is capable of rejecting parameter perturbations of all inductances and the rotor resistance. The appropriate choice of the model employed, allied with slidi
