PURPOSE:To contrive to reduce weight, and to remove eddy current loss and heat evolution of a transformer by a method wherein an organic matter ferromagnetic material is used as the core of the transformer. CONSTITUTION:A core 3 wound with coils, 1, 2 generates an AC voltage corresponding to the turn ratio of the primary winding and the secondary winding to the secondary side coil 2 in conformity to the Maxwell equations according to AC input from the primary side. When electric conductivity of the core 3 is indicated by (delta), an eddy current can be expressed by deltaE, and when the organic matter ferromagnetic material constructing the core 3 thereof is an insulator, (delta) becomes as deltaapprox.=0, eddy current is not flowed, and loss and heat evolution are small. Moreover, when the closed core 3 is used, AC magnetic flux to the outside is also hardly generated. Moreover, when the orgnaic matter ferromagnetic material is used, formation of the core in one body is also facilitated. |
