In this paper a novel multilevel current source inverter structure is proposed. This inverter is likely to be used in low/medium power applications. The proposed topology is analyzed and then compared with conventional inverters in order to validate the superiority of the proposed inverter. In this topology, all the desired current levels can be obtained using lower number of circuit devices. The number of required circuit devices is an essential factor, affecting technical and economic aspects of the system. The overall costs, circuit size, reliability and the control complexity are dependent directly to the number of required elements, including DC current sources, power semi-conductor switches and related gate driver circuits of switches. The proposed inverter is simulated to validate its practicability. Also, the experimental results are provided to demonstrate the good performance of the suggested converter. The simulation and experimental results are in good agreements which show the effectiveness of the proposed inverter.
