ABSTRACT:
A three-phase voltage stiff convertor (SR) has two six-pulse partial convertors (SR1, SR2). The alternating voltage terminals of the partial convertors are connected to a transformer (TR) with the aid of which the resultant alternating voltage of the converter is formed as the difference between the alternating voltages of the partial convertors. Each partial converter has a separate direct voltage source (C1, C2). The converter has control members (SD) which control the two partial convertors which a mutual phase displacement alternating between +150.degree. and -150.degree..
