In this paper, a new structure of a three-phase hybrid multilevel inverter is proposed. Proposed three-phase multilevel inverter is comprised of less number of IGBTs and gate drivers. Also, due to the fact that the number of DC sources is low and there aren’t electrolytes capacitors, the control strategy for generating desirable voltage is simple. Proposed inverter is comprised of three single phase H-Bridge inverters, one three phase H-Bridge inverter and auxiliary cells for increasing number of output voltage levels. This inverter is compared from the point of views of number of components, number of DC sources and blocking voltage with common inverters. Also, the calculation of loss for proposed inverter is done and it is compared from the point of view of loss with other three-phase inverters. Finally, the results of simulation that is done in PSCAD/EMTDC software package and experimental results are presented to validate the performance of the inverter.
