ABSTRACT:
The output of a deflection operational amplifier is coupled through a dissipation circuit to a deflection yoke coil of a stroke written cathode ray tube for deflecting an electron beam on the tube screen. A feedback circuit is coupled between the coil and the inverting input of the amplifier to control the current through the coil. The dissipation circuit comprises a dissipative resistor, such as an incandescent lamp, and a shunt connected bypass capacitor. The dissipation circuit dissipates power during coil steady current conditions such as exist during slow movement or hold of the electron beam on the screen when voltage across the coil is low but coil current may be high. Thus the power otherwise dissipated in the amplifier output transistors is dissipated in the dissipation circuit. The bypass capacitor passes high frequency deflection signals to the coil during coil high instantaneous current conditions corresponding to fast movement or slewing of the electron beam on the tube screen.
