Abstract

PURPOSE:To prevent generation of vertical bright and dark stripes that appear on the picture of cathode-ray tube by consuming ringing energy generated in a fly-back transformer by a specified resistance element provided in a primary coil and ground of a transformer. CONSTITUTION:An inductance element 10 is provided between a primary coil 7 and a DC power source 9 of a fly-back transformer, and a capacitance element 11 and a resistance element 12 are connected between the connection point of the inductance element 10 and the primary coil 7, and ground. High frequency ringing generated in a secondary coil 8 generates ringing current in the primary coil 7 by transfomer connection. As the inductance element 10 becomes high impedance for high frequency ringing current, ringing current flows through the path of the capacitance element 11 and the resistance element 12, and ringing energy is consumed by the resistance element 12 and attenuates rapidly.
