Stability of input voltages of a three-level inverter NPC fed by photovoltaic sources

In this paper we study the stability of input voltages of the cascade consisting of a photovoltaic inverter and a three-level structure NPC, feeding a synchronous machine with permanent magnets (PMSM) commissioned by the speed command flow oriented. For this, we first present the modeling of the Pho...

Description
Summary:In this paper we study the stability of input voltages of the cascade consisting of a photovoltaic inverter and a three-level structure NPC, feeding a synchronous machine with permanent magnets (PMSM) commissioned by the speed command flow oriented. For this, we first present the modeling of the Photovoltaic, then modeling and strategy to control the inverter three-level structure NPC. In the end, to address the midpoint fluctuation and instability of input voltages at the terminals of the inverter, proposed a solution consisting of a bridge clamping which gave promising results.
