Abstract

In a frequency converter whose line power converter can be connected to either direct current, or single-phase alternating current, the primary winding of a transformer (T) that has two secondary windings is connected to the a.c. voltage. The line power converter consists of four GTO or IGBT switching terminals (1, 2, 3, 4), of which pairs are connected in parallel. The switching terminals connected in parallel (1, 2, 3, 4) are connected together via a secondary winding (T1, T2) each, that has a center tap. If direct current is supplied, the center taps are connected to the intermediate circuit, and if alternating current is supplied, the four switching terminals (1, 2, 3, 4) are connected in parallel via the transformer (T). The necessary changes for the differences in the connections between direct-current and alternating-current feed are made by switches (7-15). Thus the number of switches is reduced by eliminating inductors.
