DEFINITION

Classification: 363/1

CASCADED OR COMBINED, DIVERSE CONVERSIONS IN WHICH THE FREQUENCY OR PHASE OR COMBINED CONVERSION IS WITHOUT INTERMEDIATE CONVERSION TO D.C.:

That is, the system must be within the class definition and include means to effect a differing sequence or combination of at least two of the following operations: 1. Current conversion; 2. Phase conversion; 3. Frequency conversion
