<p>A horizontal deflection circuit capable of performing various corrections. It is characterized by grounding one end of a first parallel circuit connecting a first switching element 11, a first damper diode 12, and a first resonance capacitor 13 in parallel, connecting the other end of the first parallel circuit to one end of a second parallel circuit connecting a second switching element 21, a second damper diode 22, and a second resonance capacitor 23 in parallel, and further connecting the other end of this first parallel circuit to a direct-current power source terminal through a primary winding of a flyback transformer 6, grounding the other end of this second parallel circuit through a series circuit of a horizontal deflection coil 4 and an S-curve correction capacitor 5, grounding the connection middle point of the horizontal deflection coil 4 and S-curve correction capacitor 5 through a parallel circuit of an intermediate pincushion distortion correction circuit 60 and a horizontal linearity correction circuit 70, and installing switching element control means 40 for switching the first switching element 11 by a horizontal drive signal, and controlling the OFF start timing and OFF period of the second switching element 21. <IMAGE></p> |
