TLDR
In this paper, a multilevel cascade voltage source inverter with separate DC sources is described, which is applicable to high voltage, high power applications such as flexible AC transmission systems (FACTS) including static VAR generation, power line conditioning, series compensation, phase shifting and voltage balancing.Abstract:
A multilevel cascade voltage source inverter having separate DC sources is described herein. This inverter is applicable to high voltage, high power applications such as flexible AC transmission systems (FACTS) including static VAR generation (SVG), power line conditioning, series compensation, phase shifting and voltage balancing and fuel cell and photovoltaic utility interface systems. The M-level inverter consists of at least one phase wherein each phase has a plurality of full bridge inverters equipped with an independent DC source. This inverter develops a near sinusoidal approximation voltage waveform with only one switching per cycle as the number of levels, M, is increased. The inverter may have either single-phase or multi-phase embodiments connected in either wye or delta configurations.read more
