<p>PURPOSE:To reduce adverse effect due to the surface effect in the winding and realize better coupling capability and thereby to improve electrical power transmission efficiency and electrical insulation performance for extending operation life of a product, making small as much as possible and improving safety of the apparatus by reducing quantity of electrical insulating materials to be used as much as possible and by lowering a leakage inductance and stray capacitance between windings. CONSTITUTION:At least two pairs of single winding coils A, B are stacked internally and externally for a core 13 and serial windings 12a, 12b are internally and externally provided opposed with each other for winding in the inverse directions with each other. The internal end of a common winding 11a as the internal end of an internal single winding coil A and the external end of a common winding 11b as the external end of an external single winding coil B are set as a grounding ends 14a, 14b, the external end of serial winding as the external end of the internal single winding coil A and the internal end of serial winding as the internal end of the external single winding coil B as a high voltage end 15, moreover the boundaries between the common winding of each single winding coil and serial windings as low voltage ends 16a, 16b, and these single winding coils are electrically and mutually connected in parallel.</p> |
