A Grid-Connected Multilevel Current Source Inverter and Its Protection for Grid-Disconnection

الملخص EN

Traditionally DC-AC converters are considered with voltage source inverters (VSI); although less studied and discussed, it has started recently to be used current source inverters (CSI).

Another possibility for DC/AC conversion is the multilevel configuration.

This paper shows experimental operation and simulation analysis of a grid-connected multilevel current source inverter (MCSI), which includes a circuit for equipment safety reasons due to grid disconnections.
