摘要

本文报道了应用于模块化多电平变换器(MMC)的两种不同调制技术的性能比较。本文主要研究了移电平脉宽调制(LS-PWM)和最近电平控制(NLC)。这个比较集中在输出电流和开关频率的总谐波失真(THD)上。在分段线性电路仿真(PLECS)环境中对作为逆变器工作的三相MMC进行了建模和仿真，以评估所研究的每种调制的性能。

Performance of Modular Multilevel Converter under LS-PWM and NLC Modulation

This paper reports a performance comparison of two different modulation techniques applied to the modular multilevel converter (MMC). Level-shifted pulse-width modulation (LS-PWM) and the nearest level control (NLC) are studied in this work. This comparison focused on total harmonic distortion (THD) of the output current and switching frequency. A three-phase MMC operating as an inverter is modeled and simulated in the Piecewise Linear Electrical Circuit Simulation (PLECS) environment to evaluate the performance of each modulation studied.
