Horizontal deflection circuit

A horizontal deflection circuit comprising:

• a first parallel circuit in which a first switching element, a first damper diode and a first resonance capacitor are connected in parallel, one end of the first parallel circuit being grounded, the first parallel circuit being operative to generate a first pulse;
• a second parallel circuit in which a second switching element, a second damper diode and a second resonance capacitor are connected in parallel, one end of the second parallel circuit being connected to the other end of the first parallel circuit, the second parallel circuit being operative to generate a second pulse;
• a horizontal deflection yoke having one end connected to the other end of the second parallel circuit and the other end connected to one end of a sigmoid (S-shaped) distortion characteristic correction capacitor;
• and a flyback transformer having one end connected to a DC power source and operative to deliver operation current to the first and second switching elements to synthesize the first pulse from the first parallel circuit and the second pulse from the second parallel circuit to generate a deflection current for driving the horizontal deflection yoke,
• the horizontal deflection circuit comprising:
• an integration circuit for integrating a horizontal drive signal inputted thereto;
• a first comparison•latch circuit for comparing a signal from the integration circuit with a first level to latch comparison result;
• a second comparison•latch circuit for comparing a signal from the integration circuit with a second level to latch comparison result;
• a first drive circuit for driving the first switching element in accordance with an output of the first comparison•latch circuit;
• a second drive circuit for driving the second switching element in accordance with an output of the second comparison•latch circuit;
• and
• control means for controlling the second level.
