To improve an image bend in a white peak condition.

This high-voltage stabilization circuit, including a voltage resonance converter of a self-oscillating switching frequency controlled type, using an orthogonal control transformer on a primary side thereof and a voltage resonance circuit or a current resonance circuit on a secondary side thereof as a combined resonance converter, is structured so that a control signal, corresponding to a high DC voltage level and ripple voltage, is supplied to a control winding of the orthogonal control transformer and the inductance of an inductance winding (drive winding) is variably controlled. The control winding of the orthogonal control transformer is set, so that a magnetomotive force is maintained and the time constant is small, by winding a plurality of wires NC1, NC2, NC3 in a bundle manner. Thus, high-speed transient response characteristics can be improved.
