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.
