【発明の詳細な説明】 〔発明の技術分野〕 この発明は、発電出力の合成を効率良く行なうことがで
きる熱電子発電方法に関するものである。TECHNICAL FIELD OF THE INVENTION The present invention relates to a thermoelectron power generation method capable of efficiently synthesizing power generation outputs.

起電力が発生する熱電子発電素子が知られていた。Conventionally, the emitter electrode and collector electrode are insulated with an insulator such as ceramic, and gas is sealed between the emitter and collector at an appropriate pressure. The emitter electrode is heated to a high temperature and the collector electrode is cooled to a low temperature. Then, a thermoelectron power generation element in which a DC electromotive force is generated between both electrodes has been known.

条件および経済性が悪いという欠点があった。However, since the power generated by each element is small, it is necessary to connect the elements in parallel to obtain practical power, but in this case the output current is large and the voltage drop in the circuit is large. . For example, even if a large conductor having a cross section of 500 m 2 is used as a power line for 1 Kw of power, a voltage drop of about 0.12 volt occurs at a distance of 1 m (round trip line length of 2 m), resulting in a line loss of about 160 watts. In addition, it is necessary to insert a resistor between each element in order to compensate for the output difference of each element, which complicates the electric path and also causes a power loss in this resistor to reduce the power generation efficiency. was there. In order to reduce the output current, it is possible to increase the voltage by connecting the elements in series.In this case, the difference in the heating status of each element causes an output difference, and the current value of the low output element is the current of the circuit. Will be controlled, and the synthesis efficiency will be reduced. In order to eliminate such a defect, a converter for converting to AC and boosting to a voltage that is easy to handle is provided near each element, and AC output from the converter may be connected in series and parallel to extract electric power. However, there is a drawback that the locational condition of installation and the economical efficiency are poor.

In order to achieve such an object, the present invention superimposes an alternating signal on the electromotive force generated from each thermoelectron power generating element to generate an intermittent output,
A large number of these are connected in series and parallel to obtain electric power. Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an embodiment.

る。FIG. 1 is a circuit diagram showing an embodiment of the present invention. In the figure, 1 is a thermoelectron power generation element, 2 is a voltmeter, 3 is an ammeter, 4 is a transformer, and 5 is a power source for generating an alternating signal.
The thermoelectron power generation element 1 is composed of an emitter 1, a collector 1b, and an insulating member 1c, and a transformer 4 includes iron cores 4a and 1c.
It is composed of coils 4b and 4c on the secondary and secondary sides.

れる。In the device configured as described above, in the thermoelectron power generation element 1
When the emitter 1a of 1 is heated and the collector 1b is cooled, a DC electromotive force is generated between both electrodes.
It is supplied to the next coil 4b. Since the alternating signal from the power source 5 is superimposed and supplied to this signal, the potential of the emitter 1a and the potential of the power source 5 become equal to the coil 4b of the transformer 4 having a load. Current begins to flow from point a, which current becomes maximum at point b, and emitter 1a
The voltage is cut off at the point C where the potential of 1 and the potential of the power source 5 become equal.
Therefore, as shown in FIG. 2 (b), the current flowing through the coils 4b, 4c has an intermittent half-wave waveform synchronized with the signal period of the power source 5, and the magnetic flux change shown in (c) occurs in the iron core 4a. The voltage shown in (d) is induced in the coil 4c.
This voltage has a value corresponding to the turn ratio of the coils 4b and 4c, and if the turn ratio is set appropriately, a voltage that is easy to handle can be obtained.

を埋め合わせ、連続した交流出力となる。If such circuits are connected in series and parallel as shown in FIG. 3, it is possible to obtain high power and high power output and reduce power loss in the electric circuit. The alternating signal from the power source 5 is connected to the coil 4b-1 and the coil 4b-2 so that the phase is inverted (a phase difference of 180 ° in electrical angle is generated) to connect the coil 4c-1 and the coil 4c-. The current i 1 and the current i 2 generated in 2 are intermittent outputs with different phases as shown in FIGS. 4 (a) and 4 (b), so by superimposing two types of outputs, A continuous alternating current output can be obtained as shown. FIG. 5 is a circuit diagram showing an output superimposing method. In the figure, 6a and 6b are switching elements, and 7 is a series body formed by connecting S secondary coils 4c of the transformer 4 for generating the current i 1 shown in FIG. 3 in series. Are connected in parallel, and only the coil portion on the secondary side is shown. Reference numeral 8 shows the portion that similarly generates the current i 2 . In the circuit configured as described above, a current of i 1 × P is taken as I 1 and is taken out from the switching element 6a, i 2
A current I 2 of × P is taken out from the switching element 6b, and each output current is a voltage that is S times the transformer output voltage. Then, the switching elements 6a and 6b
Is synchronized with the cycle of the AC signal and alternately opened and closed every half cycle, the currents I 1 and I fill up the intermittent portions, respectively, and become a continuous AC output.
