Mathematical Treatment of Rectification Phenomena

By Fourier series analysis of the no-load voltage waves of multiphase tube rectifiers, the direct current component, the ripple voltage of the various harmonic frequencies, the available transformer output, and the harmonic composition of the supply current are obtained and tabulated for various cases. The effect of any unbalanced direct current component in the secondary circuit on transformer operation is described, and practical conclusions as to design are drawn. The effect of smoothing networks is considered, as well as the efficiency of utilization of the tubes in various multiphase combinations
