In a multilevel converter, the voltage and current ratings of the switches play important roles in the cost and realisation of the multilevel converter. In all structures, the currents of all the switches are equal to the rated current of the load. However, this is not true for the voltage. A lower magnitude of the blocking voltage on switches shows that a smaller voltage is applied at the terminal of the switches of the topology, which is considered an advantage. Suppose that the maximum magnitude of the blocking voltage of switches (Eswitch) is indicated by the following equation
