Decentralized supply system with renewable energy based on quasi-eight-level inverter

Renewable energy resources available locally are ideally suited for providing electricity supply in remote areas. This report describes design and layout of a special single phase supply system with high voltage quality and low power electronics expenditure through application of a special quasi-eight-level inverter output voltage shape at four-level-inverter circuit configuration. Simulation results are presented, a laboratory model is in finalizing state (to be described in full paper). In addition, an advanced strategy is presented for handling heavy load conditions and high power output motors.
