<p><P>PROBLEM TO BE SOLVED: To eliminate an inconvenience caused by irregular magnetic flux distribution, magnetic flux leakage, or inductance leakage, related to a thin transformer used for a power convertor such as a small switching power source and an inverter. <P>SOLUTION: An insulating board 1 is provided with a plurality of slits 5 at a regular interval into which protruding parts 45 of a magnetic body 44 are inserted at a regular interval. On the upper surface of the insulating board 1, a primary-side conductor 21 constituting a primary-side conductor pattern 2 is so provided as to circulate zigzag the slits 5. The primary-side conductor 21 includes eight sections extending in the length direction of the slits 5, with the ends connected with a short primary connection conductor 22 (seven in total) to zigzag fold back, constituting the primary-side conductor pattern 2. On the lower surface of the insulating board 1, a secondary-side conductor 31 constituting a secondary-side conductor pattern 3 is provided in the slits 5. <P>COPYRIGHT: (C)2004,JPO</p> |
