Abstract
This article; is a contribution towards the improvement of the control of the three-phase two-level and multi-level photovoltaic inverter, with a new control strategy, by the sinusoidal (SPWM) and space vector (SVPWM) control for a nonlinear load., so that the latter produces a voltage wave closer to that of the grid than that supplied by a conventional inverter. This contribution is based on the strategies of indirect control of the active and reactive powers injected by this inverter into the grid, to respond, in terms of cost and energy efficiency, to the problems encountered with the photovoltaic inverter. After comparing the results of the two systems, our findings suggest that the current THDi of the interlaced (multi-level) inverter is lower than that obtained with the two-level inverter, providing higher quality waveforms, reducing current and losses caused by high-frequency harmonics. The simulation results demonstrated the effectiveness of these techniques proposed in this work.
