Description of the Related Art Recently, an electric vehicle, which has a motor to obtain a driving force without discharging exhaust gas, has been spotlighted as a pollution-free vehicle. Here, in the electric vehicle, in addition to the power supply device that drives the motor, a power supply device that drives auxiliary devices such as wipers and headlights is required, and a large capacity power supply device is required. Inevitably, a power transformer incorporated in this power supply device is also large in size, and therefore an increase in size of the power supply device cannot be avoided.

の要因となっていた。FIG. 8 shows a schematic arrangement of a conventional power transformer. For example, a primary winding 33 and a secondary winding 34 are provided around a bobbin 32 in which an I-shaped core member 31 is inserted.
Are coaxially wound at different positions on the upper and lower sides. Further, FIG. 9 shows another example. After the primary winding 33 is wound around the bobbin 32, the secondary winding 34 is wound outside the primary winding 33. .. In any of these, the primary winding 33 and the secondary winding 34 are connected to the bobbin 32.
The bobbin 32 is inevitably increased in height because it is wound around the periphery of the bobbin in the vertical direction, and the size of the power transformer is increased, resulting in a large power supply device.
In particular, in this type of transformer, the insulation distance (creeping distance) between the primary and secondary windings must be increased, and
Since it is necessary to sufficiently insulate the windings from each other, an increase in the size of members for the insulation has been a factor in increasing the size of the device.

As a result, the mileage of the automobile is not extended and the speed is reduced, which is not economical.

源トランスの小型化を図ることができる。As described above, according to the present invention, the primary windings and the secondary windings are sufficiently insulated from each other and at least one of the primary and secondary windings is sufficiently insulated. Since a flat plate-like one is used as the next winding so as to insulate the core members from each other so as to be overlapped with each other, the height dimension is reduced, so that the power transformer can be downsized.
