摘要
本文对小波调制的原理和方法进行了简单介绍,针对小波调制无法调节输出电压的问题,向小波调制引入了调制度的概念,通过对逆变器输出电压进行傅里叶分析,从理论上证明了引入调制度的小波调制的可行性。最后,通过SIMULINK建立开环与闭环的仿真模型,证明引入调制度的小波调制的优越性。
This paper introduces the principle and implementation of the wavelet modulation technique, and points out the problem that wavelet modulation technique cannot adjust the output voltage. To solve this problem, this paper introduces the concept of modulation ratio to wavelet modulation, analyzes the output voltage of inverter by Fourier transform, and proves the feasibility of wavelet modulation with modulation ratio theoretically. Finally, by building SIMULINK model, the superiority of wavelet modulation with modulation ratio is oroved.
