Study and Control of a Power Electronic Cascade using Photovoltaic Cell-Multilevel Inverter

In this paper, we study the performances of the cascade of the photovoltaic cell with the multilevel neutral point clamped (NPC) voltage source inverter (VSI). In the first part, we remind the model of the double stator induction motors (DSIM). Then, we develop knowledge and control models of this inverter using the connection functions of the semi-conductors. After that, we propose a PWM strategy to control this converter. In this part, the inverter is fed by constant input DC voltages. In the last part, we study the performances of the constituted by two photovoltaic cells – two three-level NPC VSI - DSIM. The results obtained confirm the good performances of the proposed cascade.
