PURPOSE:To reduce high-voltage variation by selecting the primary inductance of a flyback transformer so that said inductance is approximately equal to the inductance of a high-voltage reactor, and the inductance varies automatically. CONSTITUTION:The value of the peak voltage is kept at a constant level without regard to a high-voltage load by varying the synthesized inductance of an inductance Lp of a primary coil 10 of a flyback transformer 8 and an inductance Ly of a deflection yoke 2. For this purpuse, a core which is characterized by the large variation ratio of the specific permeability in the actual application region is used, and the variation of the high-voltage load and the variation of the specific permeability are made to be proportional, thereby the value of the peak voltage is kept at an approximately constant voltage. |
