一种改进的三电平空间电压矢量调制算法
An improved SVPWM control algorithm for three-level inverter
摘要
Abstract
Conventional algorithm of three-level NPC inverter was introduced.For the disadvantage and shortage,an improved SVPWM algorithm with low computational overhead based on judging of three phase voltages and voltage-second balance principle was proposed in this paper.This algorithm can not only effectively simplify the calculation and reduce calculation time greatly,but also achieve the same control effect as traditional SVPWM.Furthermore,this algorithm does not need to perform the sine and cosine calculations,and thus it is more convenient and effective than the traditional SVPWM algorithm.Finally,the proposed SVPWM algorithm was verified by the experimental results.关键词
