<p>Insulative housings are provided for enclosing a plurality of semiconductor rectifiers which form valve-pairs of a plural-bridge-circuit converter. In each of said housings a valve pair of the bridge circuit which is at a higher electrical potential relative to ground is disposed above a valve pair of a bridge circuit which is at a lower electrical potential relative to ground. The housings are spaced sufficiently from one another to provide sufficient insulation between the A-C phases. Further, the space occupied by the lower potential valve pair in a housing serves to insulate the higher potential valve pair therein from ground.</p> |
