In this paper a developed symmetric and asymmetric cascaded multilevel inverter is proposed. In asymmetric mode, the values of DC voltage sources are defined in a way that the number of output levels gets more than the condition when the symmetrical DC sources are used. In this regards, to calculate the required magnitudes of DC links several solutions are proposed. It’s obvious that the proposed topology can increase the number of output voltage levels using lower number of circuit devices. Comparison study validates the superiority of the proposed inverter. Provided simulation and experimental results confirm the practicality of proposed structure.
