摘要
三电平逆变器是目前电力电子与电力传动学科研究的热点之一,但其控制算法也要比传统的两电平逆变器复杂很多,一般采用便于数字实现的空间矢量脉宽调制(SVPWM)的方法来控制。本文介绍了SVPWM算法控制三电平逆变器的实现方法和具体步骤,最后给出了用Matlab/Simulink仿真的结果,表明了三电平逆变器的优点,同时对于深入理解算法原理和控制过程也具有一定的参考价值。
At present three-level converter is one of the hot spots in the study of electronics and power transmission, but its control algorithm is more complex than the traditional two-level converter.So the method of space voltage vector pulse width modulation （SVPWM）, which can be realized by digital tools easily Is often used to control the three-level converter. The simulation steps of SVPWM algorithm are introduced and simulation results are given by Metlab/Simulink, verifying the advantages of three-level converter.
