Phase-shifted PWM strategy of a seven-level single-phase current source inverter for grid-connection systems

This paper presents a detailed analysis of a seven-level single-phase current source inverter for grid-connection systems. The aim of this research was to control high power factor operation, injecting a sinusoidal current flowing into the utility grid. The proposed two-stage power conversion strate...
