摘要

逆变器的主要缺点是总谐波失真(THD)和谐波。本文主要进行了谐波和三次谐波的研究。采用级联的多电平逆变器拓扑结构来抑制逆变器在其输出处产生的谐波。级联多电平逆变器是最有效的燃料电池或电池存储的电力。电池具有低额定电压，级联逆变器输入必须具有低电压才能实现230v输出。仿真工作采用SIMULINK/MATLAB软件进行。研究了三相负载下逆变器的输出谐波。比较了3电平和5电平级联多电平逆变器与传统逆变器驱动的谐波和THD。多电平逆变器拓扑结构的研究抑制了谐波和THD。

Comparison of harmonics and THD suppression with three and 5 level multilevel inverter-cascaded H-bridge

The major drawback of an inverter are Total Harmonic Distortion (THD) and Harmonics. The study of harmonics and THD are carried out in this work. The cascaded multilevel inverter topology is incorporated to suppress the harmonics produced by the inverter at its output. The cascaded multilevel inverter is most effective with fuel cells or battery stored power. The cells have low voltage ratings, the cascaded inverter input must be of low voltages to achieve 230v output. The simulation work is carried out with SIMULINK/MATLAB. The harmonics at output of inverter with 3 phase load is studied. 3 level and 5 level cascaded multilevel inverter's harmonics and THD are compared with traditional inverter drive. The study of multilevel inverter topology suppresses the harmonics and THD.
