| Abstract |
This paper presents the design of a new current controleer for a three-level inverter using neural networks (NNs). From the past experience, the unbalance of DC-link voltage in the three-level inverters causes a low power factor and an increased harmonics to induction motors. The proposed current control scheme offers "tight DC-link voltage balancing" for the inverter along with nonlinear mapping of essential switching patterns and fault tolerance, which are inherent characteristics of NNs. Both computer simulation and experimental results show that the proposed new current control scheme provides an excellent fault tolerance characteristic compared with conventional hysteresis and sinusoidal pulse-width-modulation (SPWM) current control to loss of one phase information. |
