Abstract: In this paper analysis of 3-Terminal and 5-Terminal hybrid (cross breed) micro grid using Fuzzy logic controller is proposed. The cascaded H-bridge interfaces between supply and DAB converter. The DAB (Dual Active Bridge) converter connects between cascaded H-bridge and load. By using Zero sequence voltage (ZSV) and inner current controller improvement in grid current and voltage balance are achieved. To boost the grid current and unbalance voltage, 49 ruled fuzzy controller-based scheme is used. The analysis of the concept mainly deals with maintenance of power quality and uninterruption in power supply by tuning and Fuzzy logic controlling. The cascaded H-bridge hybrid micro grid with 3-terminal or 5 terminal would have better performance only if there is balanced voltage as well uninterrupted grid current. Fuzzy logic-based controller performances are analyzed through simulation results.
