Modified grid-connected current source inverter for multi-string PV system

In this paper, the principle of a power conditioning unit for multistring PV power generation system is proposed. The proposed power conditioner is based on the current source inverter (CSI) topology. All PV strings are connected in parallel to a DC bus through the modified wave-shaping circuits. Th...
