Abstract

The post-fault reconfiguration of the inverter's voltage and harmonic distortion Multilevel Inverters (MLI) is performed. In order to make use of the redundancy in the inverter, three operational conditions have been introduced. They are healthy, defective and reconfigured techniques. Therefore, to study the harmonic content of line toneutral voltage, an accurate analytical model is developed. To verify two different fault conditions are applied. To determine the harmonic content and the RMS value of the line-to-neutral voltages, a reconfiguration is used. This technique will reduce problems in a way that is effective. Through simulation, you can see that the model proposed gives precise results. Power conditioning when neutral is in place, for unbalanced loading conditions as well as harmonic content analysis required by certain grid interconnection standards, such as AS4777 or IEEE1547. In the proposed project the 5-level multilevel inverter has been discussed. And the THD is 34.6% in extension paper the 7-level multilevel inverter will be analyzed with the same conditions as described in proposed paper, and THD response will be (20-22) %.
