一种改进的三电平逆变器SVPWM控制算法
An improved SVPWM control algorithm for three-level inverter
摘要
Abstract
In the traditional three-level space vector pulse width modulation (SVPWM) algorithm,the sector judgment is computationally complex since the sector is divided into triangles and hexagons.In addition,the switching frequency is high because the seven-segment switching sequence is adopted.For this reason,a new SVPWM control algorithm for three-level inverter is proposed,in which the sector judgment is simplified by dividing the sector into quasi hexagons,and the new four-segment switching sequence is adopted to reduce the switching frequency.Simulation results show that the total harmonic distortion grows down with the switching frequency decreasing,moreover,the algorithm runtime is also decreased.关键词
