Abstract

Refinements introduced into a circuit arrangement provided with a line shunt circuit to generate a sawtooth bias current at the line frequency through a line shunt coil, in a television display apparatus, and a voltage supply circuit that switches to the line frequency, wherein the line bypass circuit comprises the bypass coil, a trace capacitor, a return capacitor, a first line frequency controllable switch and at least a winding in a transformer with a core of magnetic material, and wherein the voltage supply circuit comprises a winding of an inductive element coupled, through a diode, to the line deviation circuit, said winding being coupled to a source voltage supply by means of a second controllable switch, characterized in that the winding The inductive element is also wound on said core.
