Anais do Simpósio Brasileiro de Sistemas Elétricos 2020, 2020 This paper deals with the theoretical development, analysis, and simulation of the new topology of three-phase NPC (Neural Point Clamped) converter. The proposed 6-kW three-phase converter is connected to a three-phase electrical network and due to its bidirectional characteristics can either send energy to the grid or receive it from the grid.

Model predictive control of NPC three-level grid-tied converter based on reconstructed current [PDF]
Archives of Electrical Engineering, 2022 The neutral point clamped (NPC) three-level grid-tied converter is the key equipment connecting renewable energy and power grids. The current sensor fault caused by harsh environment may lead to the split of renewable energy.

A Highly Efficient Single-Phase Three-Level Neutral Point Clamped (NPC) Converter Based on Predictive Control with Reduced Number of Commutations [PDF]
Energies, 2018 This paper proposes a highly efficient single-phase three-level neutral point clamped (NPC) converter operated by a model predictive control (MPC) method with reduced commutations of switches. The proposed method only allows switching states with none or a single commutation at the next step as candidates for future switching states for the MPC method.
