Customer’s demand
|
|
|
We need a transformer for a plasma supply with 32 kHz and 200 A. The supply should be built up symmetrically and it should be interfered with a direct current of 100 A.
|
|
|
Solution
|
|
|
We build a transformer with a ferrite core E 80/38/20 with each 2 cores on top of each other. The secondary winding is done by one winding with central tapping. For a better coupling the primary winding is built up interlaced and is done with a high frequency wire to avoid proximity and skin losses. The secondary winding furthermore has mechanical and thermal functions by stabilizing the construction and channeling off heat via the connectors.
