摘要

研究了三电平逆变器谐波损耗最小的最优PWM策略。介绍了低、中、高速区域的不同PWM方法。结果表明，对于三电平逆变器，在所有速度区域的优化策略与两电平逆变器的最优PWM策略不同。开发的最优控制确保了三电平PWM逆变器的预定换向次数和给定的基频谐波电压值的电机谐波损耗最小。

Optimal control of three level PWM inverters

The harmonic loss-minimized optimal PWM strategy for three-level inverters is investigated. The different PWM methods for low, middle and high speed regions are presented. It is shown that for three-level inverters, the optimized strategy in all speed regions differs from the optimal PWM strategy of two-level inverters. The developed optimal control ensures a minimum of motor harmonic losses for a predetermined number of commutations of three-level PWM inverters and for a given value of the fundamental harmonic voltage.<>
