Multilevel Inverter Based on Level Switch and H - Bridge

This article proposes a topology for construction of multilevel inverter consisting of H-bridge and level switch. In accordance with the proposed topology Н-bridge inverts voltage and a switch enables to get any number of voltage levels. At that, in comparison with analogues, the above mentioned topology allows saving on expensive power keys. Moreover, a special technique has been developed to set time of level switching. 13-level inverter has been developed following the proposed topology and methodology. The article highlights the results of simulation in Matlab and an experimental inverter unit.
