Implementación de un inversor con aislamiento en alta frecuencia para sistema fotovoltaico de 12V.

Abstract

This master research project consists of the implementation of an inverter with high frequency insulation, applied to a renewable energy system. An inverter with high frequency isolation was made using a DC-DC converter, in PUSH PULL topology, applying the MPPT control technique using the P & O control algorithm. In order to increase the robustness of the inverter, the fundamental elements to be taken into account in the design of the power systems used to raise, reduce and regulate the voltage levels were studied and the DC-DC converter - topology PUSH PULL with ferrite transformer is implemented. In the simulation, the PSIM software was used to determine the parameters of the solar panel and the behavior of the P & O controller and to implement the MPPT control technique in the DC-DC converter used in the high-frequency isolation inverter. The inverter adjustment tests were done with the solar panels that are in the university.
