    Abstract - (Show below) - (Hide below)

    Gives alternative procedures for specification of ratings for semi-conductor power convertors for adjustable speed electric drive systems, especially for d.c. motor drives. Established for, but not limited to, convertors of line- or machine-commutated type, and is not meant to cover adjustable speed drives for traction applications.
