Description

[Detailed description of the invention] Energy is converted into electrical energy by a magneto-electric converter.

The present invention relates to a power generation device that obtains multiple power sources.

Conventional technology In electronic devices that use integrated circuits with different power supply voltage values, generally a power transformer whose primary side is a commercial AC power supply has a plurality of secondary windings to step up or step down the voltage. AC voltage is obtained. These alternating current voltages are passed through rectifying p-wave circuits that combine diodes and capacitors, for example, 5del),
12&ru), 200. Multiple DC voltages such as t'' are available.

In addition, a high frequency switching regulator uses a DC/AC inverter to oscillate a DC power source, such as a DC power source converted from a commercial AC power source, or a DC power source to high frequency oscillation, and a high frequency power transformer steps up and down the voltage, and a DC voltage is obtained through a rectifying Okinawa circuit.

That is, as shown in the example of FIG. 6, AC voltage from a power generation unit 9 such as a commercial power supply or a high frequency switching regulator is boosted and stepped down by a power transformer 13, and each of the AC voltages is combined with a diode 9 and a capacitor 7. DC voltage V 1 through the rectifier and smoothing circuit,
V2... is obtained.

Problems to be Solved by the Invention A power transformer 3 is used in a conventional power generation device that can obtain a plurality of alternating current voltages.

However, in general, the power transformer 3 causes losses such as magnetic loss due to leakage magnetic flux or heat loss due to heat generation due to resistance in the winding, and is also heavy.

The disadvantage is that the capacity is large. ! Furthermore, since the power transformer 3 receives a plurality of high-voltage and low-voltage power supplies, it has the disadvantage of being large and expensive in order to maintain sufficient dielectric strength up to high voltages.

Means for Solving the Problems The present invention eliminates such drawbacks of the conventional power source and provides a power generation device that obtains multiple DC power sources instead of one power source.

Output from a rotating body that rotates around a rotating shaft, with multiple magnetoelectric transducers and diodes l attached close to the permanent magnets in a magnetic cylinder in which permanent magnets are arranged along the cylindrical circumference around the rotating shaft. This is a power generation device that connects a plurality of cylindrical capacitors and a choke coil provided on the outer periphery of a magnetic cylinder to obtain a plurality of DC voltages.

As the working permanent magnet and the magnetoelectric transducer move relative to each other, a frequency and voltage related to the speed are obtained, which are rectified and smoothed to obtain a DC voltage.

As shown in the drawings, a plurality of permanent magnets 2 divided into upper and lower stages are arranged along a cylindrical circumference centered on a rotating shaft 1 to form a magnetic cylinder 3. Inside this magnetic cylinder 3, there are a plurality of magneto-electric transducers 4 that can pass close to the permanent magnet 2 and are divided into upper and lower stages, such as a combination of a magnetic core and a coil, for converting magnetism into electricity. magnet 2
A rotating body 5 rotated by the rotating shaft 1 is provided with a plurality of diodes 6 for rectifying the pulsating output induced by the magnetic flux of the rotating body 1. Further, a plug-in or sintered capacitor 7 and a cylindrical choke coil 8 are fixed to the outside of the magnetic cylinder 3' to form a power generation section. Further, the magnetic cylinder 3 and the rotating shaft 1 of the rotating body 5 are connected by a conductive medium 10 such as a brush or a slimp ring that conducts electricity.

If a drive source is connected to the rotating shaft 1 of the rotating body 5 and the rotating body 5 is rotated, the pulsating voltage induced in the magnetoelectric transducer 4 will cause the conductive medium 10 to flow every time the magnetoelectric transducer 4 approaches and passes the permanent magnet 2. After that, a plurality of smooth DC voltages l and v2 are obtained by the capacitor 7 and the York coil 8.

If there is a difference of twice as much between the permanent magnet 2 or the magnetoelectric transducer 4, which is divided into two upper and lower stages, when the rotating body 6 is rotated, the output from the magnetoelectric transducer 4 that is in contact with the upper stage will be as shown in Fig. 3 (a). ), the output from the magnetoelectric transducer in contact with the lower stage has a relationship twice that of the frequency shown in FIG. 3(c). Here, the pulsating voltage from both magnetoelectric converters 4 is integrated via a capacitor 7 and a choke coil 8.

Further, as another application example of the power generation device of the present invention, it can be used as a power source for a drive motor such as a printer or a rotating machine such as a cooling fan. Generally, power is supplied to a rotating machine as shown in Fig. 4, in which power is supplied from an AC power supply 11 to the rotating machine 12, and a DC voltage is obtained by rectifying and smoothing a plurality of AC voltages obtained by a power transformer 13.

The power generation unit 1 is generated by rotating the rotating body 5 using the rotating machine 12 as a driving source.

Note that by attaching a flywheel to the rotating shaft 1, uneven rotation can be reduced and output stability can be obtained.

Furthermore, although the magnetic core and coil have been described for the magnetoelectric transducer 4, a Hall element or a magnetoresistive element can also be used.

In the method shown in FIG. 5, the volume can be reduced by more than twice as much.
