Parallel Operation of Split-Source Inverters for PV Systems: Analysis and Modulation for Circulating Current and EMI Noise Reduction

To satisfy the ever-increasing requirement from load side and improve the power quality through harmonic content reduction, the paralleled converters’ structure is seen to be an interesting solution. However, paralleled converters, in which the same dc and ac sides are shared, suffer from a major challenge related to the excessive circulating currents due to the difference in the induced common-mo...
