Fault tolerant activity is a vital component of grid tied PV took care of Cascaded H-Bridge (CHB) converter, where the converter works persistently with faulty circumvent cells. Subsequent to bypassing the faulty cells, the quantity of sound cells diminishes, the accessible dc interface voltage lessens and dynamic force among the stages become inconsistent. Subsequently, the converter produces unequal and twisted grid flows. In addition, the greatest receptive force traded with the grid gets diminished with the accessible DC connect voltage. This work proposes a novel ANFIS controlled zero sequence voltage infusion method for adjusting the grid flows and forestalling over balance in every cell of the converter. The proposed strategy expands the receptive force ability of the converter during post fault condition. Furthermore, it additionally helps in equivalent dynamic and responsive force stream in each period of the converter. An ANFIS system is proposed in this paper to carry out the zero sequence voltage expansion in the converter. The proposed idea is checked through PC recreation and exploratory outcomes.
