PROBLEM TO BE SOLVED: To provide a high frequency horizontal deflection and high-voltage circuit preventing an increase in loss caused by a decrease in an inductance of a deflecting coil and deterioration in a characteristic caused by an increase by decrease in the number of turns, in a deflecting coil circuit. SOLUTION: Firstly, a 2nd resonance synchronous switching by FET21 is carried out on a horizontal deflection circuit consisting of a primary winding 13 of a deviation transformer and a switching transistor 10; a connection is made so that a voltage impressed on a deflecting yoke 16 may serve as a max; and also a deflecting coil voltage is utilized for a timing adjustment of a synchronous switching, and thereby a correction means required for a deflection is obtained. Secondly, a primary winding 13 of a deflection transformer and a primary winding 45 of a high-voltage transformer are operated under a low magnetic coupling, and excessive energy of a voltage generated in the primary winding of the high-voltage transformer 100 is regenerated to the power source by forming a switching circuit and thereby a high-voltage control is achieved. |
