<p>PURPOSE:To obtain a high frequency transformer having low copper loss even when it is brought into a high frequency state and a winding can be formed easily. CONSTITUTION:The title transformer consists of a primary side copper foil winding 1, composed of a recessed type copper foil electrode and a 180 deg.-rotated inversed recess type copper foil electrode which is constituted in such a manner that a surface-insulated copper foil winding is turned back in bellow form, a secondary-side copper foil winding 2, which is composed of a recess type copper electrode and a 180 deg.-rotated inversed type copper foil electrode constituted in such a manner that a surface-insulated copper foil winding is turned back in bellow-like form and interlocked alternately with the primary-side copper foil winding 1, and a core which is inserted into the recess and the inverted recess of the copper foil electrode.</p> |
