<p>PURPOSE:To reduce the effect inflicting on a winding by the core constituting an orthogonally intersecting magnetic path by a method wherein a plurality of windings are provided on a transformer, and the core is formed in such a manner that the surfaces containing the two magnetic flux generating in the core cross at right angle with each other. CONSTITUTION:Three legs 2, 4 and 9 are provided on the core 1 of a transformer, and cap spacers 6 to 8 are provided on the legs 2, 4 and 9. Besides, cores 12 and 13 are provided on the legs 2, 4 and 9. A primary winding 51, a secondary winding 52, and tertiary windings 53 and 54 of horizontal deflection circuit are provided on the leg 4 of the core 1, and moreover, a tertiary winding 55 is provided on the leg 2. When a magnetic path is orthogonally bent many times, magnetic reluctance becomes higher, the magnetic flux 11, which passes the leg 4, passes the closed magnetic path formed with the legs 4 and 9, and the magnetic flux does not flow much to the leg 2 which has high magnetoresistance. On the contrary, the magnetic flux 10, passing the leg 2, does not pass the leg 4. The voltage induced on the tertiary winding 55 is induced by the magnetic flux 11 passing the leg 4 and leaked on the leg 2 side, and the induced voltage becomes small. The reduced voltage can be compensated by increasing the number of turns of the winding 55 and also by winding the winding 51 on the leg 2.</p> |
