摘要

本文采用磁场定向控制(FOC)方案对异步电动机(IM)驱动器的转矩和磁链进行独立控制。使用标量控制的IM驱动器的速度响应受到缓慢响应的影响，并且由于机器中的饱和而产生更多的振荡。采用磁场定向控制方案，提高了系统的速度响应。采用三电平二极管箝位逆变器代替两电平电压源逆变器，并通过空间矢量脉宽调制(SVPWM)获得PWM脉冲。在MATLAB/SIMULINK环境中对三电平和二电平逆变器馈入IM驱动器的FOC进行了仿真，比较了它们在不同工况下的性能。

Field Oriented Control of Three-Level Neutral Point Clamped Inverter Fed IM Drive

In this paper, field oriented control (FOC) scheme is employed to independently control the torque and flux of the Induction motor (IM) drive. The speed response of IM drive using scalar control suffers from sluggish response and yields more oscillation due to saturation in the machine. The speed response is improved by the field oriented control scheme. Three level diode clamped inverter is used in place of two level voltage source inverter and the PWM pulses are obtained from Space vector pulse width modulation (SVPWM) for both. The FOC of IM drive fed with three and two level inverter is simulated in MATLAB/SIMULINK environment and their performances are compared at different operating conditions.
