Abstract
PURPOSE:To suppress the dispersion of the power loss at the vertical output stage, by adjusting the amplitude of deflection through the change of the conduction period of the switching transistor performing the dischrge of capacitor for drive waveform formation. CONSTITUTION:The positive voltage appeared at the junction point between the deflection coil 8 at the output stage and the DC blocking capacitor 9 is fed as the charging power supply of the drive waveform forming capacitor 4 at the drive stage. In addition, the conduction period of the switching transistor Tr1 performing the discharge of the capacitor 4 is changed, adjusting the amplitude of deflection. Thus, the dispersion at ON period of Tr1 or the remaining voltage of the vertical output voltage to the amplitude adjustmrnt is almost held constant, suppressing the dispersion in the power loss of the output stage.
