摘要

为了在五电平逆变器中产生高质量的输出频谱，本文研究了优化后的总谐波畸变OTHD PWM与传统的多载波PWM的比较。对于OTHPWM，采用微分演化法求解非线性方程计算开关角。五电平逆变器为三相感应电动机(IM)供电。这种关联允许基于输出电压和IM电流波形的THD来评估算法的性能，转矩电机波纹。

Optimized total harmonics distortion PWM and multi-carries PWM: Comparison

In this paper, the comparison between the optimized total harmonic distortions OTHD PWM and the traditional multi-carriers PWM is studied to generate high quality output spectrum in five level inverter. For the OTHPWM, the switching angles are computed by solving a non-linear equation using the differential evolution method. The five level inverter feed a three-phase induction motor (IM). This association allows evaluating the algorithm performances on the bases the THD of both output voltage and IM current waveform, Torque motor ripples.
