Model predictive control of three-level grid-connected inverters for weak power grids

Zhejiang dianli
In weak power grids， grid-connected inverters often suffer from poor robustness and significant harmonics. Moreover， model predictive control （MPC） heavily relies on system parameters， limiting its applicability in weak grids.

Transformer-based asymmetrical embedded Z-source neutral point clamped inverters with continuous input current and enhanced voltage boost capability

, 2013
Z-source Neutral Point Clamped (NPC) inverters were introduced to integrate both the advantages of Z-source inverters and NPC inverters. However, traditional Z-source inverters suffer from high voltage stress and chopping input current.
