Abstract
A transformer having a bobbinless winding assembly positioned on a base includes a primary winding having multiple radially-spiraling turns of a wire and a secondary winding including a substantially planar annular disk having a radial gap defined therein. A primary winding having first and second primary windings including multiple radially-spiraling turns of wire with free ends extending from outer turns and a method of forming the same is provided. A secondary winding having a planar annular disk with a radial gap defined therein and a method of forming the same is also provided.
Claims4
A transformer apparatus comprising:
- a base;
- a bobbinless winding assembly disposed on the base, the assembly comprising:
- a primary winding including an electrically conductive wire having a plurality of substantially co-planar radially-spiraling turns of the wire;
- a secondary winding aligned co-axially with the primary winding, the secondary winding including a substantially planar disk having a radial gap defined therein, the primary and secondary windings having a center axis defining an interior void along the center axis;
- a core positioned in the interior void, the base positioned on the exterior of winding assembly;
- a toroidal current-sense transformer positioned on the base, the current-sense transformer defining a center hole therein;
- and
- the primary winding including a free end passing through the center hole.
