A novel multilevel current source inverter (MCSI) configuration is introduced in this paper. The ability of
handling with asymmetrical DC sources is one of the substantial advantages of the proposed inverter.
In asymmetric mode, by appropriate selection of DC sources magnitude, a considerable increase can be
obtained in the number of output levels without any manipulation on inverters’ hardware. In MCSIs, the
number of required circuit devices is very important because the overall costs, circuit size, reliability and
control complexity are dependent on them directly. The proposed inverter can generate all desired current
levels using a lower number of elements. Besides, it is known that reduction of number of switches from
conventional inverters imposes an undesired increase in total semiconductor device power (SDP). But, the
total SDP of the proposed inverter is kept equal to conventional inverter. To validate the superiority of the
proposed inverter, a full comparison is provided. Also, the computer simulation and experimental results
are presented.
