Abstract

The core of the transformer is applied layer-by-layer, by physical-chemical methods, to a winding, following the magnetic lines of force of the winding. The resulting advantages are small dimensions, low loss, low leakage, low noise and mechanically stable transformers which can be automatically produced.

Manufacturing Low Loss and Low Leakage Transformers

The core of the transformer is applied layer-by-layer, by physical-chemical methods, to a winding, following the magnetic lines of force of the winding. The resulting advantages are small dimensions, low loss, low leakage, low noise and mechanically stable transformers which can be automatically produced.

First, the winding 1 is produced, using short winding lengths. By galvanic or chemical deposition or vaporization, core material 2 is applied to winding 1 while energizing the latter and causing the core material to arrange itself according to the lines of force obtained.

After an appropriately thin layer of core material is deposited, the process is interrupted pending the application of a thin layer 3. The process is subsequently continued for the application of the next layer of core material 2. A core 4 having the cross-section required is formed in successive steps. The individual layers of core material 2 are separated from each other by thin insulating layers 3.
