Diseño e implementación de un inversor con seguimiento y enganche a la fase de la red eléctrica

Abstract

As technology advances and the levels of environmental contamination increase due to different factors caused by humanity, the use of clean energy has been potentiated, so much so that they have been implemented from large-scale systems to produce large amounts of energy for industry even small residential facilities. Therefore, this article describes the design and implementation of a DC / AC inverter, which has an apparent power of 50 VA at 110 VAC, from a 12 VDC battery that obtains the power supply by half of a solar panel of so many watts and such dimensions. Subsequently, a PLL (Phase Locked Loop) circuit is implemented in order to monitor and correct phase coupling with the electrical network, thus obtaining a minimum and practically negligible phase shift to ensure effective injection of the power supply. When the installed system comes into operation, accurate information is displayed locally on the total power generated by the system, the total power injected and the phase difference between the two waves. This prototype is developed and implemented to further promote the use of renewable energy in our country, generating the least possible impact on the planet's environment.
