Design and implementation of a prototype of a single phase converter for photovoltaic systems connected to the grid

Abstract

Resumo -The usage of electrical energy generation with alternative sources is increasing significantly, due to the general concern about the environment and generation with nonrenewable sources. This fact encourages the development of technologies and new researches, to come up with solutions to allow the connection the new systems to the grid in a safe and trustable way. This work presents the project and construction of a prototype of 1,44[kW] monophasic converter for photovoltaic panels, considering the operation in connection with the grid (127[V], 60[Hz]).For the synchronism between the photovoltaic system and the AC grid a PLL (phase-locked loop) was implemented, carrying out the angle detection in the grid. Experimental and simulated results are presented to confirm the operation of the designed and implemented prototype.

“…Technological developments play an important role in the transition from fossil fuel consumption to renewable energy. Technological developments are increasing rapidly with the researches in this field in recent years (Reis et al, 2015). It is an advantageous solution to transfer the energy produced in small power PV systems to the grid via single phase (Arafa, Mansour, Sakkoury, Atia, & Salem, 2016).…”
