ABSTRACT:
A static convertor with forced commutation has at least one phase group connected between two busbars. The or each phase group has two series-connected branches with the point of connection therebetween constituting a phase terminal of the group. To the busbars there is connected a commutating circuit comprising commutating thyristors, commutating capacitors and commutating inductors common to the phase group(s). A two-terminal network, having inductive impedance at least at higher frequencies, is connected directly to the busbars and in operation a power flow between the two-terminal network and the convertor takes place. Since the network is connected directly to the busbars, the power flow does not pass through the commutating inductors and the convertor losses are minimized.
