Abstract: PURPOSE:To obtain a high voltage, various DC voltage and a deflection current with less fluctuation against a change in a current of a high voltage winding and to eliminate horizontal amplitude fluctuation by providing a pulse transformer to obtain various DC voltage through rectifier circuits provided to its secondary winding. CONSTITUTION:Various DC voltages are obtained from a secondary winding of a pulse transformer T2. A stabilizing DC power supply EB applied to the pulse transformer T2 and an input voltage Vcc applied to a flyback transformer T1 in terms of DC are cut off by a diode D2 and the input voltage Vcc applied to the flyback transformer T1 is controlled to be varied such that a high voltage EH is made constant against a change in a current 18 through a high voltage winding A of the flyback transformer. Since a constant voltage from a stabilized DC power supply EB is fed to a horizontal deflection coil Ly through the pulse transformer T2, a horizontal current (iy) is constant even when the current IH is changed. Thus, the fluctuation of the various DC voltage including the high voltage EH against a change in the current IH and the fluctuation of the horizontal amplitude are prevented.
