摘要

建立中压逆变器的方法有很多种。本文研究了目前市场上两种非再生型中压源逆变器的特性。所研究的每个逆变器在电路拓扑结构上都有很大的差异，这反过来又导致了性能特征的差异。介绍了一种5电平中性点箝位型中压PWM逆变器的工作特性和机械结构。在描述电机运行不同速度时的电流谐波时，给出了特别的细节。论文的第二部分研究了P. Hammond发明的中压驱动器(参见IEEE Trans)。印第安纳州,达成。第33卷，no。1, 1997)。该逆变器由Robicon公司制造，并安装了GE信号电子设备。本文对GE-Robicon混合逆变器样机的性能进行了测试和描述。

Performance of medium voltage multi-level inverters

There are many ways to build medium voltage inverters. This paper studies the characteristics of two types of nonregenerative medium voltage source inverters that are in the market place today. Each inverter that was investigated has major differences in circuit topologies, which in turn led to differences in performance characteristics. The operational characteristics and the mechanical construction of a 5 level neutral point clamped medium voltage PWM inverter are described. Particular detail is given in describing the current harmonics present at different speeds of motor operation. The second part of the paper studies a medium voltage drive which was invented by P. Hammond (see IEEE Trans. Ind. Appl., vol.33, no.1, 1997). The inverter was built by Robicon and retrofitted with GE signal electronics. The performance of that GE-Robicon hybrid inverter prototype was measured and is described in this paper.
