摘要
首先介绍了一种简单且实用的三相电压型逆变器数学模型,然后在分析空间矢量脉宽调制(SVPWM)算法原理的基础上,详细推导了SVPWM算法,并对其传统算法进行了过调制处理,使算法得以改善。在MATLAB/SIMULINK环境下建立了SVPWM控制的三相电压型逆变器仿真模型。给出的仿真结果表明逆变器模型以及SVPWM算法的正确性和可行性。
Firstly, a simple and practical mathematical model of three-phase voltage source inverter was introduced in this paper. Then based on the principle of space vector pulse width modulation （SVPWM） technique, the SVPWM algorithm was derived in detail, and the traditional algorithm was improved by over-modulation. The simulation model of three-phase voltage source inverter controlled by SVPWM was established in MATLAB/SIMULINK. The simulation results demonstrate the accuracy and feasibility of the inverter model and SVPWM algorithm.
