摘要:This paper describes about the efficient control strategy in parallel operation of inverters in commonalternatingcurrent(AC) bus which is used in real time applications like uninterrupted power supply (UPS), medicalequipments and many. The control system for parallel operation of inverters consists of two main loops; the firstcontrol loop is parallelism control over the feedback inductor current to modify the input voltage to the filter. Thesecond loop is voltage control over the output voltage of each individual voltage source inverter connected to thecommon AC bus. Here control system is implemented in neuro fuzzy control strategy which ensures less precise,flexible, better stability in control. The proposed control strategy ensures the voltage source inverters(VSI) operating incommon AC bus with proper sharing of load current, redundancy and without any needs of communication exchangebetween inverter modules .The parallel operation of inverters in common AC bus with proposed control system areverified both in theoretical and experimental results.
