Abstract

PURPOSE:To connect an S-shape correction circuit directly to a power supply by supplying a DC current to the juncture between an S-shape correcting capacitor and a horizontal deflecting coil constituting a series resonance circuit from a DC power supply via a diode. CONSTITUTION:The release and short-circuiting are repeated by turning on and off a switching transistor TR. A DC power supply E supplies a DC current through a series resonance circuit consisting of a deflecting coil LY and an S-shape correcting capacitor CS and via a diode D'. That is, a current is supplied via the diode D' when the terminal voltage produced at the capacitor CS by the series resonance circuit of the coil LY and the capacitor CS is smaller than the power supply E. Then the supply of the current is discontinued when the terminal voltage of the CS is smaller than the power supply E.
