摘要：

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.
