ABSTRACT:
A circuit arrangement for the demagnetization of color television receivers, in particular small battery fed receivers, comprising first switch means for charging a first capacitor immediately before demagnetization and second switch means adapted to be activated after the charging of said first capacitor for causing the capacitor to discharge through the demagnetization coil with short lasting current pulses of alternating direction. The arrangement comprises a second and smaller capacitor, which is charged and discharged by the current flowing through the demagnetization coil, this sequence being repeated in cyclic order.
