Abstract
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,, a first damper diode,, and a first resonance capacitor,in parallel, connecting the other end of the first parallel circuit to one end of a second parallel circuit connecting a second switching element,, a second damper diode,, and a second resonance capacitor,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,, grounding the other end of this second parallel circuit through a series circuit of a horizontal deflection coil,and an S-curve correction capacitor,, grounding the connection middle point of the horizontal deflection coil,and S-curve correction capacitor,through a parallel circuit of an intermediate pincushion distortion correction circuit,and a horizontal linearity correction circuit,, and installing switching element control means,for switching the first switching element,by a horizontal drive signal, and controlling the OFF start timing and OFF period of the second switching element
