A New Three-Phase Multilevel Inverter for Electric Drive

Nowadays, Multilevel inverters have received a lot of interest from researchers. In this paper, a unique architecture for a 7-level inverter with just six adjustable switches is presented. The proposed topology offers multiple perks, notably in the field of embedded systems such as electric traction drives. This topology is noticed for its capacity to generate 7-level output voltage with less number of switch, it is designed from three-level nine-switch inverter. This combination offers a high level of flexibility and control. To assess the efficacy of the proposed 7-level inverter, simulations on an inductive load were performed, followed by powering a controlled PMSM electric traction actuator. The outcomes of the simulations revealed the efficiency and performance of the proposed topology. These results underscore the importance of this research, as it contributes significantly to the design of a new 7-level inverter topologies that is useful for electric traction drives and various other embedded systems.
