<P>PROBLEM TO BE SOLVED: To provide a ferrite core and inverter transformer which can be made more efficient by a one-input and multiple-output structure and can be further reduced in the number of components and cost and has a high installation area reduction effect. <P>SOLUTION: The ferrite core comprises a leg portion 2 for a primary coil around which a primary coil 7 is to be wound, and leg portions 3, 4 and 5 for a secondary coil around which secondary coils 8, 9 and 10 are to be wound. These leg portions 3, 4 and 5 are magnetically coupled by a coupling portion 6. There are three or more leg portions 3, 4 and 5 for a secondary coil as opposed to just one leg portion 2 for a primary coil, and the leg portions 3, 4 and 5 for a secondary coil are formed at such positions that they may have nearly the same magnetic resistance with respect to the leg portion 2 for a primary coil. To be more specific, the distance between each of the leg portions 3, 4 and 5 for a secondary coil and the leg portion 2 for a primary coil is set nearly the same. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
