Abstract :
E. B. Shand: From the standpoint of practical design calculations, I believe that the formulas in the complex forms given are not generally applicable, due to the fact that the accuracy of design calculations is limited by a number of factors not considered in the paper. An instance of this may be found in equation (20) for voltage ratio. This expression may be simplified very greatly by introducing coefficients obtained directly from the converter field form without going through the process of actual harmonic analysis, which have a greater degree of accuracy than those of the calculated field form.
