Abstract

Multilevel inverters with hexagonal voltage space vector structures have improved performance of induction motor drives compared to that of the two level inverters. Further reduction in the torque ripple on the motor shaft is possible by using multilevel dodecagonal (12-sided polygon) voltage space vector structures. The advantages of dodecagonal voltage space vector based PWM techniques are the complete elimination of fifth and seventh harmonics in phase voltages for the full modulation range and the extension of linear modulation range. This paper proposes an inverter circuit topology capable of generating multilevel dodecagonal voltage space vectors with symmetric triangles, by cascading two asymmetric three level inverters with isolated H-Bridges. This is made possible by proper selection of DC link voltages and the selection of resultant switching states for the inverters. In this paper, a simple PWM timing calculation method is proposed. Experimental results have also been presented in this paper to validate the proposed concept.

一种带对称三角形的多级12面多边形矢量的开口绕组IM驱动器
采用六边形电压空间矢量结构的多电平逆变器与双电平逆变器相比,具有更好的感应电机驱动性能。通过使用多层十二面(12面多边形)电压空间矢量结构,可以进一步减少电机轴上的转矩波动。基于十二角电压空间矢量的PWM技术的优点是在全调制范围内完全消除了相位电压中的五次和七次谐波,并扩展了线性调制范围。本文提出了一种逆变电路拓扑结构,通过级联两个具有隔离h桥的非对称三电平逆变器,可以产生具有对称三角形的多电平十二角电压空间矢量。这可以通过适当选择直流链路电压和选择逆变器的由此开关状态来实现。本文提出了一种简单的PWM定时计算方法。本文还给出了实验结果来验证所提出的概念。
