  • Horizontal deflection amplifying apparatus
    Patent number: 5606229
    Abstract: A horizontal deflection amplifying apparatus for use in an automatic main power supply such as that for a cathode ray tube is provided. The apparatus uses a microprocessor for the connection of capacitors to a horizontal deflection coil (yoke coil) by controlling the switching operation of relay switches. To prevent the drive transistor of the deflection coil driver from being destroyed or the horizontal deflection coil from being damaged due to excess current, the capacitors are connected or disconnected while the power supply voltage is off (i.e., at a 0V state) and the supply voltage is then re-applied. Thus, the horizontal deflection amplifying apparatus can be safely driven.
