A 5-LEVEL MIXED FRAMEWORK FOR BALANCING THE DC-LINK CAPACITOR

The suggested topology supplies a compromise between different component counts to attain a great loss distribution, avoid direct series connection of semiconductor products, keep your balanced operation of electricity-link capacitors and keep the amount of pricey components for example capacitors and switches low. The characteristics from the suggested topology are investigated and in comparison with other available topologies. Simulation answers are presented to verify the performance from the ripper tools for medium current programs. This paper proposes a brand new five-level hybrid topology mixing options that come with neutral point clamped and flying capacitor inverters. For that suggested inverter, a hybrid modulation strategy is needed because of the hybrid structure from the topology. The needed modulation technique is developed and the whole process of the suggested topology isanalyzed.
