Abstract:
A horizontal deflection circuit comprising a centering circuit designed to change a direction of a current which is supplied to a deflection yoke, thereby adjusting a position of a raster in a horizontal direction, said centering circuit comprising:a switching element including first and second ends, said first end of said switching element being connected to a node positioned between a first end of a first S-shaped capacitor and the deflection yoke, said second end being connected to a first end of a second capacitor, and wherein a second end of said first S-shaped capacitor and a second end of said second capacitor are connected to a ground; switching element control means for controlling an on- and off-state of the switching element, thereby controlling a current to be supplied from the first S-shaped capacitor to the second capacitor and controlling a current to be supplied from said second capacitor to said first S-shaped capacitor, wherein said currents supply said deflection yoke; a coil connected at a first end to the node of the second capacitor and the switching element, and at a second other end to a direct-current power supply; and a diode connected in parallel to the switching element and having an anode connected to the node of the second capacitor and the switching element.
