DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power generation device that converts ghee into electrical energy using a magnetoelectric converter to obtain a plurality of power sources.

Conventional technology In electronic equipment in which integrated circuits with different power supply voltage values are used, in general, a power supply transformer whose primary side is a quotient fl'1 AC power supply is boosted by multiple secondary windings. I am getting multiple AC voltages with different fc. These alternating current voltages rj: A plurality of direct current voltages such as 5 volts, 12 volts, and 200 volts can be obtained through rectifying F-wave circuits each including a diode and a capacitor.

In addition, a high-frequency switching regulator uses a 1G current/AC inverter to oscillate a DC power supply such as a DC power source or a battery that converts a commercial AC power supply into high-frequency oscillation, and the voltage is stepped up and down by a high-frequency power transformer, and a DC voltage is obtained through a rectification Okinawa circuit.

That is, as shown in the example of FIG. 5, the AC voltage from a power generation unit 8 such as a commercial power supply switch or a high frequency switching regulator is converted into a plurality of stepped-up and stepped-down AC voltages by a power transformer 12 and then passed through a diode 6 and a capacitor 7, respectively. Through the combined rectifier and smoothing circuit, DC voltages V1, V2 and
... is obtained.

Problems to be Solved by the Invention A power transformer 12 is used in a conventional power generation device that can obtain an alternating current voltage of a certain number of screws.

However, in general, the power transformer 12 generates heat due to magnetic disintegration due to leakage magnetic flux or heat generation due to resistance in the winding.
'11, etc. and weight.

The disadvantage is that the capacity is large. Another drawback is that the power transformer is expensive.

Means for Solving the Problems The present invention eliminates the drawbacks of the conventional art and provides a power generation device that obtains a plurality of DC power sources from a single power source.

Inside a magnetic cylinder, the magnetic poles of permanent magnets are arranged along the circumference in a cylindrical shape centered around a rotating shaft connected to a rotating drive source.
A plurality of pulsating voltages from a rotating body rotating around a rotating shaft 1, which is close to a permanent magnet and equipped with a plurality of magnetoelectric transducers and diodes 6, are connected to a plurality of capacitors 7 provided on the outer periphery of the magnetic cylinder. It is a direct current type power generation device that generates pressure.

The relative movement of the working permanent magnet and the magnetoelectric transducer induces electricity each time the magnetoelectric transducer passes a position of the permanent magnet. Strength and number of permanent magnets.

The frequency and voltage related to the moving speed are obtained, and this is rectified and smoothed to obtain a DC voltage.

Embodiment FIGS. 1 and 2 show a plan view and a longitudinal sectional front view of an embodiment of the power generating apparatus according to the present invention.

As shown in the drawings, a magnetic cylinder 3 is formed in which a plurality of permanent magnets 2 are arranged along a cylindrical circumference centered on a rotating shaft 1. It is possible to pass into the magnetic cylinder 3 in close proximity to the permanent magnet 2.

For example, a rotating body 5 that rotates around a rotating shaft 1 is provided with a plurality of diodes 6 attached to a magnetic core and a coil for rectifying pulsating output induced by the magnetic flux of a permanent magnet 2. A power generation section 9 is formed by fixing a plug-in or sintered capacitor 7 to the outside of the magnetic cylinder 3.

The magnetic cylinder 3 and the rotating shaft 1 of the rotating body 5 are connected by a conductive medium such as a brush or a slip ring that conducts electricity.

Now, when a drive source is connected to the rotating shaft 1 of the rotating body 5 and the rotating body 5 is rotated, pulses are induced in the magneto-electric transducers 4 and 4' each time the magneto-electric transducer 4 approaches and passes the permanent magnet 2! The + current voltage passes through the conductive medium 1 and is outputted from the capacitor 6 as a plurality of DC voltages Vl and v2.

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. 3, in which power is supplied from an AC power supply 10 to the rotating machine 11, and a DC voltage is obtained by rectifying and smoothing a plurality of AC voltages obtained by a power transformer 12. Voltage Vl, V2
was used as a power source for electronic equipment. However, even if the kinetic energy of the rotating machine 11 is available, it cannot be used, but as shown in Fig. 4, the rotating machine 11 is rotated by the power source 13 regardless of whether it is AC or DC, and the rotating machine 11 is used as the driving source. The body 5 is rotated and the power generation unit 8 is operated to simultaneously generate a plurality of DC voltages V1. V2 is obtained.

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 transducers 4 and 4', a Hall element or a magnetoresistive element can be used.

Effects of the Invention As described above, according to the present invention, an inexpensive power generation device with good efficiency and small volume can be obtained, and the means shown in FIG. 1 has a dielectric strength of 5 kg71? can be kept more than the conventional 5
It is more than twice as large, and the volume can be reduced by the means shown in FIG.
