Additive Manufacturing of Spiral Windings for a Pot-core Constant-flux Inductor

Constant-flux inductors (CFIs) are designed to have a more uniform flux density in the core for efficient use of the magnetic material and higher inductance density. However, these inductors generally require unique winding structures that are difficult to manufacture by conventional means. In this article, we applied a paste-extrusion 3-D printer to fabricate spiral windings with varying turn-by-...
