Abstract

In this paper, a new configuration for symmetrical and asymmetrical multilevel inverters is proposed. In asymmetric mode, different algorithms are suggested in order to determine the magnitudes of DC voltage sources. The merit of this topology to the conventional symmetric and asymmetric inverters is verified by the provided comparisons. This topology uses a lower number of power electronic devices such as switches, IGBTs, diodes, related gate driver circuits and DC voltage sources. Owing the lower amount of requirements, it has lower total costs and needs less installation area. Also the control strategy has less complexity. The proposed converter can generate all the desired output voltage levels with positive and negative values. To confirm the practicability of the proposed inverter, simulation and experimental results are provided which are in good agreements.
