Description
Summary:In this paper, a new T-type inverter topology based on multi-state switching cell is proposed. The topology presents five-levels voltage before of 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 5kW prototype is presented in this work.
