Five-Level T-Type Inverter Based on Multistate Switching Cell.

In this paper, a new T-type inverter topology based on multistate switching cell is proposed. The topology presents five-level voltage before the output $LC$ filter, providing high-order harmonics that are easily filtered. In this topology, the output filter ripple frequency is twice the switching frequency, therefore reducing the magnetic weight and volume. Other characteristics of the inverter are current sharing through the devices, facilitating its losses' dissipation, due to increased contact area and few involved components in the current flow path. In order to verify its feasibility, a design example, as well as experimental results, for a 5-kW prototype is presented in this paper. [ABSTRACT FROM AUTHOR]
