Abstract

The research and improvement of new power electronics inverters are mandatory to improve the viability of distributed generation through renewable energy sources usage. In this context, the power electronics plays a fundamental role and, usually, Photovoltaic (PV) energy sources provide low DC voltage that needs voltage boost, a good input maximum power point tracking (MPPT), and low total harmonic distortion (THD) for the output AC voltage/current. These criteria may be economically determinant in the future use of renewable energies such as wind and solar once the most expected applications with renewable sources are the grid tied or grid connected, where no local energy storage is needed and all benefits of distributed generations could be achieved.

Moreover, experimental evaluations of a PV grid-tied inverter are shown in order to demonstrate the feasibility of the proposal. This study presents a three-phase tri-state buck–boost integrated inverter suitable for stand-alone and/or grid-connected photovoltaic (PV) energy applications. The usage of the special features of the tri-state operation coupled with a modified space vector modulation allows the inverter to present a remarkable degree of freedom for the controllers’ design, that is, input and output can be independently controlled.
