N2 - In this paper, direct power control strategy used in three-level neutral point clamped (NPC) converters is discussed. With the theory of instantaneous power, it gets the deep relations between power (active power and reactive power) and space voltage vectors. After the analysis, considering the special issues in three-level NPC converters, such as the excessive dv/dt and fluctuation of neutral point potential, a direct power control (DPC) strategy for three-level NPC converters is proposed. Simulation results show the correctness of the new DPC control strategy.
