摘要

The transformer has a three-shank core mounted in a housing and carrying several coils in concentric arrangement. The coils consist of an even number of parts mounted along the core shank axis, the minimum number of coil parts being four. The parts of one coil, coupled to the supply source, are connected in parallel. The other coil is connected to the rectifiers and has the phases of half of its parts delta connected, and those of the other half star connected. The delta and star phase connections of the coil parts (42 - 45) of the winding (4), coupled to the rectifiers connected in series.
