工业中唯一不变的是技术的变化。引起这一变化的主要发明之一是逆变器。电力电子器件将直流电以所需的输出电压和频率转换为交流电，称为逆变器。功率逆变器的输出电压是失真最小的纯正弦波形，这在实际中是很难获得的。为了使逆变器输出的正弦波失真最小，引入了多电平逆变器的概念。使用多个直流电压源作为输入并通过功率半导体器件的适当布置来产生阶跃电压波形。这里讨论了几种多电平逆变器的拓扑结构。它们在牵引、高压直流输电等方面得到了应用。
The only constant in industry is the change in technology. One of the major inventions which invoked this change is inverters. Power electronic devices which convert DC power into AC power at desired output voltage and frequency is known as an inverter. The output voltage of a power inverter is to be a pure sinusoidal waveform with minimum distortion, which is practically difficult to obtain. In order to make pure sinusoidal waveform from the inverter with minimum distortion the concept of multilevel inverters was introduced. A stepped voltage waveform is generated with the use of number of DC voltage sources as the input and by appropriate arrangement of the power semiconductor-based devices. Several topologies of multilevel inverters are discussed here. These find their application in traction, HVDC transmission, etc.
