TRANSFORMER |
| 摘要 |
There is provided a transformer in which leakage inductance can be adjusted arbitrarily and which can be readily processed and achieves reduction in size. The transformer includes: a primary coil (10) and a secondary coil (12); and a core (14) that forms an annular closed magnetic circuit by being arranged across the primary coil and the secondary coil. A magnetic body (15) having a cross-sectional area smaller than a cross-sectional area of the core is arranged between the primary coil (10) and the secondary coil (12) so as to interpose a spacing between both of its end parts and the core and so as to make a short-cut of the annular closed magnetic circuit. |

1. A transformer comprising:
a primary coil and a secondary coil; and a core that forms an annular closed magnetic circuit by being arranged across the primary coil and the secondary coil, wherein a magnetic body having a cross-sectional area smaller than a cross-sectional area of the core is arranged between the primary coil and the secondary coil so as to interpose a spacing between both of its end parts and the core and so as to make a short-cut of the annular closed magnetic circuit. |
