Abstract :
The paper provides a comparison of conventional with graded windings used in pulse-transformer design. A conventional winding is defined as one in which the interlayer dielectric thickness is constant over the winding length, while the graded winding is defined as one in which the interlayer dielectric thickness varies linearly over the winding length. General theoretical considerations are laid down, and four winding types are described in detail. One of the major advantages obtainable with graded windings, particularly where high potentials are concerned, is a reduction in the core volume required to meet a given specification.
