多级H桥并联变换器的谐波分析
Harmonic Analysis of Parallel Multi-level
在简要分析多重化变换器和多级H桥并联变换器系统特性的基础上，采用傅立叶分解的方法分析了多级H桥并联变换器消除低次谐波的机理，分析结果表明9个H桥并联变换器可以消除n=18k±1（k=1,2,3,…）次以外的谐波，具有减少对电网谐波污染的优点。最后，给出了PSPICE仿真和系统实验波形。
his paper simply describes the characteristics of multi-level converter and parallel multi-level H-bridge converter, then mainly analyzes the principle of neutralizing lower harmonics in the parallel multi-level H-bridge converter by means of Fourier analysis. According to the analysis, the converter consisted of 9 H-bridges can eliminates the harmonics other than n class[n=18k±1（k=1,2,3,…）], hardly pollutes the electricity grid. The simulation fulfilled by PSPICE and the experimental waveforms are also given.
