Deadbeat Control Strategy of Circulating Currents in Parallel Connection Syst…

Module parallel connection for three-phase VSC can increase the system level effectively. However, the circulating currents problem will occur. The circulating currents will distort the three-phase currents, increase the power loss and decrease the system efficiency.Anovel deadbeat circuiting currents control method is proposed in this paper. Based on the analysis of the average model of parall…
