Abstract (en)
[origin: EP2348516A1] The transformer (10) has a printed circuit type insulating element (13) and conductive coils (11, 12) positioned in a superposed manner on opposite faces of the insulating element. The conductive coils are is circular, elliptical, square or rectangular shapes. The coils are in a form of flexible or rigid plastic plate. Each coil includes flat metallic winding turns provided with central ends. Electric wires are positioned at a surface of the insulating element. The coils are separated by the insulating element. An independent claim is also included for an electrical apparatus comprising a printed circuit on which electrical components are arranged.
