This paper deals with the development of a multiobjective optimization algorithm programmed in Matlab, which allows to obtain a voltage vs frequency ratio (V/F) that decreases the voltage value as the frequency is reduced by maintaining the total harmonic distortion (THD) at levels very close to 0% over the entire frequency range of operation. The multiobjective algorithm is applied to a common-source cascaded H-bridge multilevel converter with maximum 15 steps per line voltage. The inverter is simulated by supplying a three-phase induction motor.
