矩阵式功率变换器用于将一个交流电源变换为另一个具有不同峰值电压和频率的交流电源。有三个输入线,正弦变化的电压是从另一个不同的相位,输出是作为一个类似的三相电源提供。矩阵转换器快速切换,以将每个输出线顺序连接到每个输入线,以试图合成规定的输出电压。开关在高频下进行,并且知道输出电压和输入与输出电流的频谱具有实际重要性。在本文中,我们确定这些光谱使用一种新的方法,它具有显着的优势,比以前的默认方法(多重傅立叶级数技术),导致一个更直接的计算。特别地,输入电流谱的确定在这里是可行的,而使用现有方法则是明显更令人生畏的过程。
Matrix power converters are used for transforming one alternating-current power supply to another, with different peak voltage and frequency. There are three input lines, with sinusoidally varying voltages which areout of phase one from another, and the output is to be delivered as a similar three-phase supply. The matrix converter switches rapidly, to connect each output line in sequence to each of the input lines in an attempt to synthesize the prescribed output voltages. The switching is carried out at high frequency and it is of practical importance to know the frequency spectra of the output voltages and of the input and output currents. We determine in this paper these spectra using a new method, which has significant advantages over the prior default method (a multiple Fourier series technique), leading to a considerably more direct calculation. In particular, the determination of the input current spectrum is feasible here, whereas it would be a significantly more daunting procedure using the prior method instead.
