Analysis and Design of High-Efficiency Hybrid High Step-Up DC–DC Converter for Distributed PV Generation Systems
TL;DR: A new hybrid high voltage gain dc–dc converter is created by merging the standard boost converter with a coupled inductor and different switched-capacitor techniques, with a single switch and no requirement of higher duty cycle values.
Journal ArticleDOI
Synthesis and Comparative Analysis of Very High Step-Up DC–DC Converters Adopting Coupled-Inductor and Voltage Multiplier Cells
António Manuel Santos Spencer Andrade,Everson Mattos,Luciano Schuch,Helio Leaes Hey,Mário Lúcio da Silva Martins +4 more
TL;DR: In this paper, a synthesis methodology for developing a set of very high step-up dc-dc converters is presented and discussed, in which three stepup techniques are combined and incorporated.
Journal ArticleDOI
Quadratic-Boost With Stacked Zeta Converter for High Voltage Gain Applications
TL;DR: In this paper, the authors proposed a new topology derived from cascaded, stacked and cascaded configuration of dc/dc pulse-width modulation converter cells in order to access the benefits of both structures in a single-stage topology with a single active switch.
Journal ArticleDOI
High Step-Up PV Module Integrated Converter for PV Energy Harvest in FREEDM Systems
TL;DR: In this paper, a single-switch dc/dc converter for the future renewable electric energy delivery and management system to implement the distributed renewable energy resources (DRER) is proposed, which is responsible for the maximum power point tracking of the photovoltaic panel (PV) module and also for the control of central energy storage device.
Journal ArticleDOI
Comparative Evaluation of Single Switch High-Voltage Step-Up Topologies Based on Boost and Zeta PWM Cells
António Manuel Santos Spencer Andrade,Helio Leaes Hey,Luciano Schuch,Mário Lúcio da Silva Martins +3 more
TL;DR: From the theoretical analysis and experimental results, the association named stacked boost–zeta with autotransformer yielded the highest efficiency and power density and resulted in the most attractive converter for the case study.
