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.

Current-Limiting Droop Control of Grid-Connected Inverters [PDF]
IEEE Transactions on Industrial Electronics, 2017 A current-limiting droop controller is proposed\ud for single-phase grid-connected inverters with an\ud LCL filter that can operate under both normal and faulty\ud grid conditions. The controller introduces bounded nonlinear\ud dynamics and, by using nonlinear input-to-state stability\ud theory, the current-limiting property of the inverter is ...
