混沌载波频率调制在双级矩阵变换器中的应用
|
摘要
拥有整流级和逆变级两部分的双级矩阵变换器(Two Stage Matrix Converter,TSMC)的输出电压含有高峰值离散谐波。为了削减在载波频率及其整数倍频率附近的谐波峰值,并且抑制谐波产生的电磁干扰(Electro Magnetic Interference,EMI)问题,本文首次将混沌载波频率调制技术(Chaotic Carrier Frequency Modulation Technique,CCFMT)应用于TSMC中。CCFMT通过使载波频率按照混沌方式变化,让单一频率处的谐波得到拓展,从而达到削减谐波幅值,满足电磁兼容(Electro Magnetic Compatibility,EMC)的要求。为了减少换流次数,提高TSMC的换流可靠性,本文中TSMC的整流级和逆变级选取了适当的调制函数和载波形状。通过TSMC的实验平台证明,本文所提出的CCFMT能够完成削减输出电压谐波峰值,抑制EMI问题。
The output voltage of the Two Stage Matrix Converter(TSMC), which has two parts of the rectifier and inverter class, contains the high peak value discrete harmonic. In order to cut near carrier frequency and the integer time frequency harmonic peaks, and suppress the harmonic produced the Electro Magnetic Interference(EMI) problem, this article first to used Chaotic Carrier Frequency Modulation Technique(CCFMT) in TSMC. CCFMT through changing the carrier frequency in the manner of chaos, make a single frequency harmonic expansion, to reduce harmonic amplitude, meet the requirements of Electro Magnetic Compatibility(EMC). In order to reduce the flow rate of the TSMC and improve the flow reliability of TSMC, the corresponding modulation function and carrier shape of the TSMC are selected. Using the TSMC experimental platform, the CCFMT is proved to be able to reduce the output voltage harmonic peak and suppress EMI problem.
