<p>PURPOSE:To make the coupling between each winding section of a high voltage coil and a primary winding close make resonance frequency high, and improve high voltage regulation by engaging coil units divided into a plurality of members with each leg of a core provided with a plurality of legs. CONSTITUTION:High voltage coil bobbins 4a, 4b are engaged with the outer periphery of low voltage coil bobbins 2a, 2b around which low voltage coils 3 are wound; high voltage coils 5 are subjected to divided winding of one layer or a plurality of layers; each of the winding sections 5a, 5b subjected to the divided winding is alternately arranged with each of the interlayer insulators 6a, 6b, thereby constituting a laminated winding structure. Each of the winding section 5a, 5b is connected in series via diodes 8c, 8d; on the output side of a final winding section of the high voltage coil 5, diodes 8a, 8b are connected in series, thereby forming a plurality of coil units 11a, 11b. These are engaged with each of legs of a core 1; primary coils 3a, 3b of the low voltage coils 3 are connected in parallel; the high voltage coils 5 are connected in series via the diode 8c in a manner that high voltage outputs are obtained by rectifying and adding.</p> |
