摘要

逆变器是任何具有电网的可再生能源转换系统将直流电转换为交流电所需的调节元件。多级逆变器已成为高压工业应用中重要的变换器拓扑结构，为可再生能源向发电容量的渗透做出了巨大贡献。本文分析了由光伏阵列供电的级联H桥多电平变流器的谐波性能。对CHB变换器的对称拓扑和非对称拓扑进行了仿真研究。利用MATLAB/Simulink平台对5 ~ 15台光伏阵列多级逆变器进行了仿真。本文还考虑了温度和太阳辐照等参数对光伏阵列的影响。

Modelling and Harmonic Analysis of Symmetrical / Asymmetrical CHB Multilevel Inverters with PV arrays

An inverter is the required conditioning element for any renewable energy conversion system with an electrical grid to convert DC to AC power. Multi-level inverters have become a vital converter topology in high voltage industrial applications and contributed tremendously to renewable energy penetration into power generating capacity. This article analyses the harmonic performance of cascaded H bridge multi-level converters fed from photo-voltaic (PV) arrays. Both symmetrical and asymmetrical topologies of CHB converter have been considered for simulation studies. The simulations of 5 to 15 multi-level inverters with PV arrays have been done using the MATLAB/Simulink platform. The effects of parameters like temperature and solar irradiation on PV arrays are also considered.
