摘要：
In this paper the performance of a neutral point clamped (NPC) three-level voltage source inverter is investigated. The inverter feeds an electric drive which is controlled by field oriented control (FOC). The improvement of the control scheme is achieved using Mamdani's fuzzy logic controller for both rotor speed and inverter current. The main issue of this work is neutral point (NP) balancing for a three-level NPC inverter combined with a new Space Vector Pulse Width Modulation (SVPWM) algorithm. The performance of the electric system is verified via Matlab/Simuline. The operation of the electric system is investigated in steady state and transient responses in both cases whether using or not the NP balancing algorithm. Finally, the ability of the proposed switching pattern generation algorithm for NP balancing is established. (C) 2012 Elsevier B.V. All rights reserved.
