DEFINITION

Classification: 363/65

Having plural converters for single conversion:

(under subclass 13) Subject matter wherein a single current conversion is effected simultaneously by a plurality of converters.

(1) Note. The converters may be connected in series, in parallel, or combinations thereof.

(2) Note. In the systems in this subclass the conversion must be only from A.C. to D.C. or from D.C. to A.C. The ordinary full wave rectifying systems are excluded because each half of the wave is rectified by a separate converter, and rectifiers are alternately effective, i.e., one half of the wave being rectified and then the other half of the wave. Full wave systems having a plurality of converters for each half of the alternating current wave are included. Likewise, polyphase systems are excluded unless one or more of the phases is provided with a plurality of converters so that a single current conversion in a phase is effected by a plurality of converters. Full wave and polyphase converter systems will be found in the other subclasses of this class.

15, and 34+, for current conversion systems where the system includes means to effect a plurality of current conversion. Examples of the systems in subclasses 34+ are systems which convert A.C. to D.C. to A.C. or which convert A.C. to D.C. to A.C. to D.C.

64, for current conversion systems which include an interphase transformer for multiplying the number of paths through the converter without multiplying the number of phases.
