ABSTRACT:
A three-phase circuit, either load impedances or transformer windings for feeding such load impedances, are connected in a delta circuit configuration by a first group of controllable semiconductor elements and in a star circuit configuration by a second group of such elements. All elements are fired, but at different phase angles for operatively establishing a star, a delta, or a mixed type of connection.
