| 摘 要： | 基于空间矢量脉冲宽度调制(SVPWM)的基本原理,在Matlab/Simulink环境下构建了3种SVPWM方法的仿真模型,通过与正弦脉冲宽度调制(SPWM)的比较表明基于SVPWM的三相逆变器具有较高的直流电压利用率,较少的输出线电压谐波和相电流谐波.该仿真模型建模方法简单,调用方便,适合于变频变压电源的仿真分析,为交流励磁发电系统的进一步研究和设计打下了基础.

| Abstract: | This paper builds simulation model of three types of SVPWM methods based on the basic principles of the space-vector pulse width modulation(SVPWM) under Matlab/Simulink;and through comparing with sine pulse width modulation(SPWM),it is indicated that the SVPWM controlled three-phase inverter has higher utilization efficiency of DC voltage,lower output line voltage harmonics and phase current harmonics.The modeling method of the simulation model is simple,and the process of transfer is convenient.The model is suitable for simulation analysis of variable frequency-variable voltage electrical source;and it offers the grounds for the further research and design of the AC excitation generating system. |
