Closed-loop current control for a grid-tied Neutral Point Clamped (NPC) inverter. The considered setup is a three-phase three-wire NPC inverter supplied by a DC source and connected to the grid.
Simple first-step guide to building NPC converters, taking as an example a 3-phase 3-level NPC converter supplied by a DC voltage and connected to a resistive load.
Neutral Point Clamped NPC converters are a family of multilevel power converters that are characterized by the use of clamping diodes for guaranteeing the proper voltage sharing across the power switches.
