摘要
研究了三相电压型逆变器SPWM调制技术,首先介绍了三相电压型逆变电路的工作原理,然后详细阐述了SPWM控制技术的工作原理,接着借助仿真软件对三相电压型逆变器SPWM调制技术进行了建模和仿真。最后通过对仿真结果的比较分析,得出改变输出频率以及调制度,可以影响到逆变器的输出电流的频率以及幅度。
SPWM modulation technology in three-phase voltage type inverter is studied, and firstly the working principle of three-phase voltage type inverter circuit is introduced , and then the working principle of SPWM control technology is elaborated. And then the modeling and simulation are made with the simulation software for three-phase voltage type inverter SPWM modulation technology. Finally, through the comparison and analysis of the simulation results, it is concluded that the frequency and amplitude of the output current can be affected by changing the output frequency and modulation.
