Neutral point clamped quasi-impedance-source inverter

In this paper a new modification of a three-level neutral-point-clamped inverter is presented. The proposed topology combines the advantages of the three-level neutral-point-clamped full-bridge inverter with those of the quasi-impedance-source inverter. The neutral-point-clamped quasi-impedance-source inverter is especially suitable for renewable energy sources. The steady-state analysis of a neutral-point-clamped quasi-impedance-source inverter in the case of continuous conduction mode is presented. The presented models as well as deduced equations are verified in a simulation.
