TRANSFORMER FOR PWM CONVERTER

摘要

PURPOSE:To perform multiplex-operation of a converter by one transformer by adequately determining the reactance and the mutual reactance of a secondary winding represented by a matrix to set the amplitudes and the ripples of the basic wave components of the AC side currents of the converters. CONSTITUTION:The secondary winding of a transformer 13 is multiple-divided to be used by a multiplex voltage PWM converter 14. The reactance of the secondary winding represented by the matrix of the transformer 13 is set the same for the secondary winding at any combined value as seen from the converter 14 side, and the mutual reactance is reduced to a value smaller than the self leakage reactance in the secondary winding.
