FREE-DOWNLOAD D Venkatramanan… – 2010
Abstract—Grid connected PWM-VSIs are being increasingly used for applications such as Distributed
Generation (DG), power quality, UPS etc. Appropriate control strategies for grid synchro- nisation
and line current regulation are required to establish such a grid interconnection and
