摘要

在多电平功率转换应用中使用了多种调制策略。本文重点研究了一种新的多载波PWM方法，并将其扩展到级联h桥多电平逆变器中。新的多载波PWM方法可以优化或平衡级联h桥多电平逆变器的开关利用率。利用本文提出的新型多载波PWM作为电压源逆变器(VSI)，对五电平级联h桥多电平逆变器进行了仿真和控制。

Novel Multi-Carrier PWM Method for a Three-Phase Cascaded H-Bridge Multi-Level Inverter

A number of modulation strategies are used in multi-level power conversion applications. This paper is focused on novel multi-carrier PWM methods which have been extended for use in cascaded H-bridge multi-level inverter. Novel multi-carrier PWM method can be optimized or balanced the switch utilization in cascaded H-bridge multi-level inverter. Five-level cascaded H-bridge multi-level inverter has been simulated and controlled with the novel multi-carrier PWM proposed in this paper to act as a voltage-source inverter (VSI)
