Three-phase multilevel inverter with high value of resolution per switch employing a space vector modulation control scheme

A special cascaded configuration of asymmetric multilevel inverter is presented in this paper. This configuration cancels the redundancy of output voltage steps and maximizes the number of levels in the output voltage. This structure is built by using series connected stages, which minimize the number of semiconductor switches, gate drive arrangements, occupying area, and cost. It is a modular type inverter model and the number of voltage levels can be increased by adding new stages without changing the previous connection. Space vector modulation has been applied as the control strategy. A prototype of the proposed inverter topology has been built in the laboratory. The attached hardware results indicate the accuracy of the proposed model, which include the topology as well as the control technique.
