Current sourcing isolated grid connected inverter [PDF]
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010 This study proposes a soft switched Output Current Sourcing (OCS) grid connected inverter that applies a high frequency isolation transformer. Current sourcing at the output implies that, ideally, the injected current will be independent of the load voltage.

A grid simulator to evaluate control performance of grid-connected inverters [PDF]
2014 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2014 Grid simulators are used to test the control performance of grid-connected inverters under a wide range of grid disturbance conditions. In the present work, a three-phase back-to-back connected inverter sharing a common dc bus has been programmed as a grid simulator.
