要がなく、装置を小形軽量にできる。[0007] A new implementation according to the present invention is one of the transformers 4.
The secondary windings 411 and 412 are divided into at least two parts, and a harmonic absorption winding 44 is provided therebetween.
4 in that a filter capacitor 31 and a resistor 32 are connected to the output terminal of the filter 4. As a result, the harmonic absorption winding 44
Is arranged between the two divided primary windings, so that the magnetic coupling with the primary windings is high. "Dense magnetic coupling" means that the leakage inductance between the two windings is small. On the other hand, winding 4 for harmonic absorption
4 is a converter winding 42 which is a secondary winding.
Since it is separated from 1,422, the magnetic coupling with the secondary winding is reduced. In other words, the harmonic absorption windings 44 and 1
The leakage inductance with the next winding is extremely small,
On the other hand, the leakage inductance between the harmonic absorption winding 44 and the secondary winding increases. Therefore, since the leakage inductance between the harmonic absorption winding 44 and the primary winding is small,
If the harmonic absorption winding 44 is provided and the filter capacitor 31 is connected to the output terminal, a harmonic absorption effect can be obtained. Of course, it goes without saying that the capacity of the filter capacitor is set to a value converted in consideration of the turns ratio between the primary winding and the harmonic absorption winding 44. The resistor 32 is a damping resistor for preventing a harmful resonance phenomenon, and is not always necessary in some cases. The design of the filter capacitor 31 is as follows.
If the inductance of L is 4 and the capacitance of the filter capacitor 31 is C, a series resonance circuit having a resonance frequency of fo = 1 / (2π√LC) is formed.
If the capacitance of the capacitor 31 is set so that the resonance frequency fo matches the fundamental harmonic frequency generated by the PWM converter, the harmonic components of the PWM converter can be effectively absorbed. The resistor 32 is a damping resistor for preventing unnecessary parasitic oscillation. With the configuration as in the present embodiment, the voltage of the harmonic absorption winding 44 can be set to a low voltage (usually around 1 kV to several hundred volts) at the same level as the secondary or auxiliary power winding.
It is not necessary to make the filter capacitor 31 and the resistor 32 high-voltage insulated, and the device can be made compact and lightweight.

1,442 are arranged. In this way, the magnetic coupling between the primary winding and the winding for higher harmonic absorption becomes denser than in the embodiment of FIG. 1, and the higher harmonic absorption characteristics are improved.

The present embodiment is an embodiment in which the harmonic absorption winding 44 is used as a power supply for the auxiliary device 8. In this way, the auxiliary device power supply winding 43 is also used as the harmonic absorption winding 44, and the winding 43 for the dedicated auxiliary device can be omitted, and the size and weight of the device can be further reduced. . In the above-described embodiment of the present invention, the case where the divided primary winding and the harmonic absorption winding are respectively connected in series has been described, but it is needless to say that this may be connected in parallel. It is.

By placing the harmonic absorption winding, a filter circuit can be connected to the low-voltage side of the transformer, eliminating the need to insulate the filter equipment at high voltage and making the filter equipment small and lightweight suitable for mounting on electric vehicles. And harmonics flowing out to the power receiving side can be effectively reduced. Furthermore, by making the auxiliary device power supply winding also serve as the harmonic absorption winding,
