Abstract
A circuit arrangement for powering a two-phase asynchronous motor having two windings which each have one end connected to one anode and both have another end connected to a third node, the nodes each being arranged to receive one of three alternating voltages whose sinusoidal fundamental waves at least substantially correspond in frequency. In this circuit arrangement, the power dissipation in the switching circuit connected to the third node is reduced by the alternating voltage applied to the third node having constant levels in periodically recurring time intervals so as to obtain a more economical dimensioning without a deterioration of the operating characteristics, particularly the loadability.
