本文描述了模块化多电平变流器的工作原理，这是一种新兴的、非常有吸引力的中高压应用拓扑。介绍了一种新的适用于任意电压等级的脉宽调制(PWM)方案，并对其进行了评估。在此基础上，对半导体损耗进行了计算，并给出了损耗分布。
This paper describes the operation of modular multilevel converter, an emerging and highly attractive topology for medium- and high-voltage applications. A new pulsewidth-modulation (PWM) scheme for an arbitrary number of voltage levels is introduced and evaluated. On the basis of this PWM scheme, the semiconductor losses are calculated, and the loss distribution is illustrated.
