<p>PURPOSE:To provide a flyback transformer for high frequency of a low voltage bobbin structure, when a low voltage coil of good voltage-resistance wherein copper loss is reduced with space winding of good combining characteristics is wounded. CONSTITUTION:Relating to a flyback transformer wherein a bobbin assembly, wherein a high voltage bobbin wound with a high voltage output coil is inserted into the outside of a low voltage bobbin wound with two low voltage input coils in parallel, contains what has been composed of a high voltage capacitor and high voltage resistor in a resin pregnant with epoxy of a resin case, on the top surface of a flange part 6 on both sides of a groove 5 formed, on the outer periphery of the low voltage bobbin 1, so that the first winding 4a of input coil is space-wound, a groove 7 for the second winding 4b of input coil to be space-wound is formed.</p> |
