<p>PURPOSE:To enable the titled item to be miniaturized and is low-cost by a method wherein at least a primary winding in windings wound to a magnetic core is formed to a parallel connecting body constituted by plural conductor connecting wires. CONSTITUTION:Each of the primary winding 2, the secondary winding 3 and the auxiliary winding 4 forming a transformer are constituted by connecting with a copper wire 21, 22, 31, 32, 41, 42 in parallel consisting of two conducting wires respectively. When the same copper winding is used, resistance value for such a D.C. of each winding in the transformer decreases to about one half because of parallel connection in comparison with a conventional transformer constituted by one winding in the each winding, although the volume of winding becomes twice if winding number is equivalent. In case that the volume of winding is the same and winding number of each winding is one half, resistance value decreases to one fourth. Accordingly, it is possible to conduct high-current even though the size is the same.</p> |
