ABSTRACT:
A circuit arrangement is disclosed comprising a converter for converting a three-phase system of sinusoidal voltages into three trapezoidal control voltages for controlling control units serving three direct cycloconverters. More particularly, in accord with the invention, the converter acts on the sinusoidal control voltages such that during each region from .pi./3 to 2.pi./3 of a half-wave of each particular voltage that voltage is reduced to .sqroot.3/2 times its peak value, while the other two voltages are amplified or increased by an amount equal to the difference between the aforesaid peak value and .sqroot.3/2 times such peak value.
