<p><P>PROBLEM TO BE SOLVED: To provide a small-sized and low-priced inverter transformer for a multiple light. <P>SOLUTION: There are provided a substantially square-shaped outside core 2 and substantially I-shaped inside cores 3a, 3b, 3c inside the outside core 2. A primary winding W1 and a secondary side winding W2 are respectively wound on the cores. Also, a magnetic flux generates in the cores 3a, 3c, respectively, by a current flowing in the primary winding W1 wound on the cores 3a, 3c, respectively, and a direction of the magnetic flux generates in a direction of subtracting from each other. The direction of the magnetic flux generated on the core 3b generates in a direction of subtracting from each other, and also the magnetic flux generated in the cores 3a, 3c and the magnetic flux generated in the cores 3b generate respectively in a direction of adding to each other in the core 3b. Further, the winding is performed so that a polarity of a voltage induced to the secondary winding W2 wound on the cores 3a, 3b, 3c has an identical polarity. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
