<p>PURPOSE:To provide a converter transformer, which has little leakage magnetic flux, is good in winding properties, is high in efficiency, is small-sized and is thin, in high quality and at low cost. CONSTITUTION:Multi-parallel conductor wires, which are wholly covered with a singular number or a plurality of insulating layers 4, are used as a primary coil 2, whereby as excess insulation among strands of the multi-parallel conductor wires is removed, a converter transformer, which reduces the material cost for the conductor wires, improves the space factor of the conductor wires in the coils, decreases a leakage magnetic flux, eliminates a disarranged winding of the conductor wires, increases a coupling of making a winding execute easily, is high in efficiency, is small-sized and is thin, is provided in high quality and at low cost.</p> |
