Title: Transformer
Inventor: AMANO TAKASHI
IPC: H01F38/08
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To improve the utilization efficiency of an iron core for reduced size by reducing a magneto-resistance. SOLUTION: A secondary coil 9 side is so formed as to be lower than the height of a central leg iron core part 4 on a primary coil 7 side. The magnetic flux of a space leakage magnetic path 10 and that based on the secondary coil 9 are parallel when viewed from the primary coil 7 of an iron core 2 while the magnetic flux based on the primary coil 7 is split into the magnetic flux of space leakage magnetic path 10 and that on the secondary coil 9 side. Since, related to the central leg iron core part 4, the cross-section area on the primary coil 7 side is smaller than the secondary coil 9 side, the magnetic flux density of the primary coil 7 side and the secondary coil 9 side is close to each other.  By reducing the cross-section area on the secondary coil 9 side of the central leg iron core part 4, the size of the secondary coil 9 is reduced while the magnet-resistance is reduced as the flat path length on the secondary coil 9 side is shortened, resulting in reduced size and improved efficiency.
