ABSTRACT:
A line deflection circuit in a television display apparatus. Between the parallel diode and the chassis there is a series arrangement of a first winding and a capacitor, a second winding being included between the switch and the voltage supply source. A diode is connected to a point of the first and to a point of the second winding and conducts in the retrace period of the deflection current. By adjusting the conduction time of the switch a trace voltage can be obtained which exceeds the supply voltage so that the circuit is suitable for battery supply.
