First, an algorithm is proposed to determine the optimal post-fault state among all possible states, which have the same maximum available voltage. Furthermore, a modified technique is proposed to calculate the references of inverter phase voltages under faulty conditions. This technique leads to a decrease in the common-mode voltage when the required output voltage is less than its maximum value. These solutions are mutually employed in the post-fault control system. Simulation and experimental results confirm the effectiveness of the proposed solutions in comparison with the existing methods in different cases. © 2017 IEEE.enArtículoATRIBUCIÓN 4.0 INTERNACIONAL CC BY 4.0 Deed10.1109/TIE.2016.2632058
