Novel 1-? Multilevel Current Source Inverter for Balanced / Unbalanced PV Sources

Rohini ^[51] | Nagabhushan ^[12]

Abstract: A new single phase multilevel current source inverter (MCSI) configuration which can generate symmetrical output current levels for both balanced and unbalanced PV sources is proposed in this paper. The proposed MCSI topology uses less number of power devices as compared to that of conventional MCSI. By using this proposed control strategy, good quality of current can be fed in to the utility when both types of PV sources operate at their respective maximum power point. Efficacy of the proposed MCSI topology is tested with two PV sources operating under partially shaded conditions i. e. the two sources are receiving different irradiation. The simulation results corresponding to the proposed configuration are presented for 500W system using MATLAB/Simulink.
