To get maximum power from Photo Voltaic (PV) panel, a DC-DC converter is operated with an active switched LC-network and fuzzy controller, which boosts the output voltage by utilizing Maximum Power Point Tracking (MPPT). In areas where solar energy abundant, PV systems offer low-cost source of electricity. Non-Polluting low maintenance are two advantages system. There several factors that can r...

This paper presents a power electronic interface (PEI) converter with three ports to connect a Photovoltaic system and a DC-microgrid to the main grid. The proposed converter is based on asymmetric Γ-source inverter, which makes two controllable ports in its DC side without utilizing any excessive DC/DC converters, which make it interesting for multi-port applications. The PEI system is expecte...

Oceans, and particularly waves, offer a huge potential for energy harnessing all over the world. Nevertheless, the performance of current energy converters does not yet allow us to use the wave energy efficiently. However, new control techniques can improve the efficiency of energy converters. In this sense, the plant sensors play a key role within the control scheme, as necessary tools for par...

The industry of solar Photovoltaic (PV) energy and its application are still booming to enhance the sustainability of the society. When PV systems are connected to the grid, challenging issues should be addressed.
