PURPOSE:To improve efficiency by reducing loss, to suppress the generation of heat, and to realize size reduction and stable operation, by allowing a horizontal deflecting circuit to stabilize a voltage by itself without using the voltage stabilizing circuit of a power source, and obtaining a self-stabilizing horizontal deflecting circuit. CONSTITUTION:The 1st parallel circuit consists of the 1st switching control element 31, the 1st capacitor 34, and the 1st and the 2nd diodes 38 and 39, and the 2nd parallel circuit consists of the 1st and the 2nd coils 41 and 42 and the 2nd switching control element 40. Further, the 3rd parallel circuit consists of the 3rd capacitor 36 and the serial circuit of the 3rd and the 4th coils 45 and 43, and the 2nd and the 3rd parallel circuits are connected in series. To this serial connection circuit, the 1st parallel circuit is connected through the 5th and the 6th capacitors 46 and 30 and astable DC voltage is applied to the capaccitor 30. Then, a horizontal deflecting coil is used as the coil 43 and the coil 45 is used as the primary winding of a fly-back transformer to constitute the self-stabilizing type horizontal deflecting circuit. |
