Abstract (en)

[origin: EP0293617A1] A high-frequency power transmitter, especially for switched-mode power supplies of sandwich construction, operating on the resonance principle, a sleeve-shaped coil former (7, 8) being seated on the centre limb (1) of at least one soft-magnetic core part (2), on which coil former (7, 8) there can be stacked, in a combinable manner, the primary and secondary windings (9, 12), of multi-part design, together with arc-shaped insulation discs or insulation spacer discs (13) to achieve defined coupling factors and defined stray inductances. <IMAGE>
