ELECTRICAL MACHINE DRIVEN BY A PULSE-CONTROLLED A.C. CONVERTER

摘要

The machine contains strands (I,II) divided into a number of n >/= 2 equal partial strands (I1, I2; II1, II2) which are magnetically largely decoupled from one another. Each partial strand is supplied from a separate converter (UI1, UI2; UII1, UII2), the clocking of converters (UI1, UI2; UII1, UII2) being shifted in phase through an angle of 2 pi /n with respect to one another for the n partial strands (I1, I2; II1, II2). ……
