Abstract (en)

[origin: EP0401490A1] In practice, the primary winding of a diode-split transformer is usually produced as foil winding in order to ensure good functional capability. In the novel diode-split transformer, the prerequisites for good functional capability of the diode-split transformer should also exist when the primary winding is not produced as a foil winding. Essentially, this is achieved by the fact that the primary winding (3) is constructed as a single-layer cylindrical coil and the end of the primary winding remote from the base (1) of the diode-split transformer is brought back to the base through a recess (6) in the coil former. <IMAGE>
