Transformer winding for power transformer, HF=LF converter, pulse transformer or Cuk-converter - has primary and secondary coils of flexible braid of insulated individual wires braided together

摘要

The winding has at least a primary and a secondary coil. A flexible braid (12) of several narrow individually insulated wires provides a high degree of coupling between the primary and secondary coils. The wires are tightly braided together either individually or with several combined in parallel. The primary and secondary coils are each formed by bundles (15, 16, 17) of a freely selectable number of individual wires. The number of wires in the primary and secondary coils may or may not be the same. ADVANTAGE - Provides almost perfect coupling between primary and secondary coils resulting in very good dynamic properties. Has low stray inductance and low cost.
