Implementation of a High-Efficiency, High-Lifetime, and Low-Cost Converter for an Autonomous Photovoltaic Water Pumping System
Joao V. M. Caracas,Guilherme de C. Farias,Luis Felipe Moreira Teixeira,Luiz Antonio de Souza Ribeiro +3 more
TL;DR: In this article, the authors proposed a new converter for photovoltaic (PV) water pumping or treatment systems without the use of chemical storage elements, such as batteries, to achieve a more efficient, reliable, maintenance-free, and cheaper solution than the standard ones that use dc motors or lowvoltage synchronous motors.
Proceedings ArticleDOI
Implementation of a high efficiency and low cost converter for a photovoltaic water pumping system
Joao V. M. Caracas,Luis Felipe Moreira Teixeira,Guilherme de C. Farias,Luiz Antonio de Souza Ribeiro +3 more
TL;DR: In this article, the authors proposed a new converter for photovoltaic water pumping and treatment systems without the use of storage elements, which is designed to drive a three-phase induction motor directly from PV solar energy.
Proceedings ArticleDOI
State space decoupling control design methodology for switching converters
Evandro de Carvalho Gomes,Luiz Antonio de Souza Ribeiro,Joao V. M. Caracas,Sebastian Y. C. Catunda,Robert D. Lorenz +4 more
TL;DR: In this article, the authors derived a new approach for analyzing dc-dc converters for feedback control design, where the control-to-output voltage transfer function of the converters, usually predicted by averaging models, and the classical feedback control techniques are replaced by the state space average state block diagram analysis.
