Diode & Neutral Point Clamped Five-Level Inverter For the Power Quality Issues

The five-level inverter is attractive for medium power applications with reduced voltage and current stress by virtue of which lower rating of semiconductors for the medium and high voltage applications. This inverter is productive for the reduced total harmonic distortions (THD) to accomplish the good quality of the power in addition to lower size of the filter components as cost effective solution for the aggressive power market. The inverter also make certain to avoid the complications of the static and dynamic voltage sharing when the power semiconductors are connected in series with a multi-leveled-inverter topology.
