As disclosed in Japanese Patent No. 13665, a single-phase or multi-phase output winding is provided on an armature part that rotates a field part by external power and faces a magnetic pole surface of the field part to form a magnetic circuit. Has been proposed, and a method of rectifying the electric energy electromagnetically induced in the output winding and extracting DC power of 12V or 24V has been proposed and put into practical use. At this time, the magnetic field inside the generator is
New edition Automotive Engineering Handbook 6th edition (published by book publishers)
As shown in Fig. 3-24 of Chapter 3 Dynamo, "When a load current flows, an approximate current of three-phase sinusoidal AC flows through the generator as described in 3.3.2. For this,
The armature (coil of the stator) constitutes a magnetic field, which interferes with the magnetic field of the rotor and causes a so-called armature reaction. For example, if a three-phase alternating current flows as shown in FIG. 3-24, a magnetic field Fa due to the armature current is generated as an armature reaction in addition to the magnetic field Fo of the rotor. As a result, a magnetic field F'is generated by both Fo and Fa, and this is a magnetic field effective for power generation. Is explained. Fo, Fa, F ', V, I

できる。To solve this problem, capacitor connecting means as shown in FIGS. 4 and 5 have been proposed. This is because the leading current Ic flowing through the capacitor is converted to the output current Ic.
By superposing it on L and advancing the vector of the magnetic field Fa by the armature current, the inside F'of the generator is increased. As a result, the output of the generator can be increased.

In addition, there has been proposed a configuration in which a capacitor is connected between all terminals of the second winding provided in the armature section, and the second winding arranged in the same manner as the output winding.

きる。Since the second winding 9 has a larger number of turns than the output winding 3, the voltage Vc electromagnetically induced in the second winding 9 is larger than the voltage V electromagnetically induced in the output winding 3. A high voltage is applied to the capacitor 8 connected between the terminals of the winding 9, and the capacity of the capacitor 8 required to obtain the predetermined advance current Ic is small. Further, since the current Ic flowing through the second winding 9 has a relatively small value, the winding may be thin, and it is not necessary to increase the size of the automobile generator by providing the second winding. . Therefore, it is possible to provide an automobile generator that is small in size and can produce a large output by using a small capacitor.

A means for separating the armature winding output terminals from each other by using an electromagnetic switch or the like, and an armature winding output terminal using the electromagnetic switch or the like for the capacitor 8 when the number of rotations becomes higher than a preset number of rotations.

合、次のようなことが考えられる。However, in the above-mentioned conventional automobile generator, when the AC voltage induced between the second winding output terminals reaches the maximum value, the second winding output is generated. When the capacitor separated from the terminals is connected between the second winding output terminals by using an electromagnetic switch or the like, the following can be considered.

点が考えられる。For example, when the contact of the electromagnetic switch is closed when the AC voltage induced between the output terminals of the second winding reaches the maximum, an excessive current flows to the capacitor. The rush current generated at this time causes the contacts of the electromagnetic switch to be welded, and the contacts are always in a conducting state, so that the capacitor cannot be separated from the second winding output terminal in the event of an abnormality. As a result, the power generation device may be destroyed, and the devices connected as a load may be destroyed. In addition, the welding of the contacts may progress, and the contacts of the electromagnetic switch may be destroyed in the worst case. At that time, there is a problem in that the capacitor cannot be connected between the second winding output terminals and the generator output is lowered.

てしまうなどの問題点が考えられる。Further, when the contact of the electromagnetic switch is opened when the AC voltage induced between the output terminals of the second winding reaches the maximum value, a high voltage or current causes the electromagnetic switch to be similar to the above. The contact is welded, and the contact is always in a conductive state, so that the capacitor cannot be separated from between the second winding output terminals at the time of abnormality. For this reason, problems such as destruction of the power generator and destruction of devices connected as a load are considered. Further, the welding of the contacts may progress, and in the worst case, the contacts of the electromagnetic switch may be destroyed. At that time, there is a problem in that the capacitor cannot be connected between the second winding output terminals and the generator output is lowered.
