摘要将三电平中点钳位（NPC）交直交变流技术和H桥级联技术相结合的五电平NPC/H桥变流器可以实现更高等级的输出电压和容量。该文研究基于集成门极换向晶闸管（IGCT）的大功率五电平NPC/H桥变流器的主电路拓扑结构,并采用模块化结构设计方式减少了杂散参数。在变流器输出中低频时采用一种改进型载波层叠正弦脉宽调制（IPD-SPWM）方法,并提出一种解决低调制度时最小脉宽问题的方法。在变频器输出高频时采用特定谐波消除脉宽调制（SHEPWM）方法来减小输出电压的总谐波畸变率（THD）,并给出计算的开关角度轨迹。实验结果验证了该文研制的变流器所采用的拓扑结构设计和调制方法的可行性,表明变流器达到了设计要求,具有良好的性能。

Abstract：With the combination of the three-level neutral-point-clamped (NPC) technology and H-bridge cascade technology, the five-level NPC/H-bridge converter can improve the output voltage and power capacity. In this paper, the topology of large power five-level NPC/H-bridge converter based on integrated gate-commutated thyristor (IGCT) was investigated, and the modular structure design was adopted to reduce the stray inductance. An improved phase disposition sinusoidal pulse width modulation (IPD-SPWM) method is used when the converter works at low and medium frequencies, and a method to solve the minimum pulse width problem with small modulation depth is proposed. The selective harmonic elimination pulse width modulation (SHEPWM) method is adopted to reduce the output voltage total harmonic distortion (THD) when the converter works at high frequency, and the trajectory curves of switch angles are given. The experimental results verify the feasibility of the topology design and pulse width modulation method proposed in this paper, and show that the converter meets the design requirements and has excellent performance.

Key words： Integrated gate-commutated thyristor (IGCT) neutral-point-clamped (NPC)/H-bridge five- level sinusoidal pulse width modulation selective harmonic elimination pulse width modulation
