This paper presents a general and yet fast multilevel space-vector modulation technique, based on orientation of reference point in terms of hexagon lines. The main advantage of the proposed algorithm is the reduced volume of calculations that consequently makes it possible for implementing on cheaper microprocessors. The introduced technique in finding the reference vector location is extended to...
This paper presents a new voltage-balancing method of five-level neutral-point clamped inverter, based on space-vector modulation redundant switching states. The proposed method uses measurement of DC-link capacitors and output phase currents in order to determine the best fitted redundancies. Due to its severe approach, the proposed method provides relatively low voltage ripples using low-capacitance...
Multilevel inverters generate low harmonic waveforms at the output, which makes them suitable for high voltage energy conversion scheme to deliver efficient high power to the loads from renewable energy sources like photovoltaic systems which are penetrating to the electric grid nowadays, significantly. In this paper a single-phase hybrid multilevel inverter based on cascading full bridge and half...
