摘要

提出了一种降低三相五电平级联逆变器谐波含量的确定性算法。该程序从一个非线性方程组出发，使用切比雪夫多项式和沃林公式，对任意指定的调制指数计算那些开关角α1和α2减少谐波幅度，以满足网格编码规范。仿真和实验结果验证了该方法的可行性。

A deterministic harmonics mitigation technique for five-level inverters

A deterministic algorithm aiming at reduction of harmonic content in three phase, five-level cascaded inverters is proposed. The procedure starts from a non-linear system consisting of disequations and, using Chebyshev polynomials and Waring's formula, for any assigned modulation index computes those switching angles α1 and α2 reducing harmonics amplitude such as to fulfill grid code specifications. Simulation and experimental results demonstrate the achievable results.
