(Prior art and problems to be solved by the invention) Traveling wave tubes used in microwave band amplifiers not only heat the filament, but also apply a high voltage to each electrode, that is, the collector, anode, and helix, with the cathode as a reference. need to be supplied. Each of these Class 341 high-voltage power supplies must be independently voltage-setting and voltage-stabilized, and must also have the ability to measure current for protection and control. Therefore, a power supply device for a traveling wave tube is equipped with a large number of inverters, a rectifier, and a current measurement function equipped with an insulating means, and when these insulating means are added together, the structure becomes extremely bulky. (Means for Solving the Problem) The present invention aims to solve such Ts problem. Supplied from a single AC power source. Two rectifier circuits are provided, and the line on the AC input side of the ml rectifier circuit and the second M
One change is made to the line on the AC input side of the tlLtni path!
This paper proposes a means for measuring current by coupling it to a device. Also that second one! i! The present invention also proposes a means for selecting one arm of the diode of the m circuit to the current flow of 2 In of the other arm. Furthermore, by connecting one end of each of the output terminals of the three rectifier circuits supplied with power from a single AC & I power supply in common and making it a cathode potential, and connecting the other end to the other electrodes, a power source for traveling wave tubes can be obtained. It is also proposed to configure the following. [Embodiment] FIG. 1 is a diagram showing an embodiment of the present invention. Inverter I generates a 1'&frequency alternating current of about 50 klIz. A high frequency high voltage is applied to the secondary winding 202 of the transformer 2 through the transformer 2. One end of this secondary winding 202 is first connected via the primary winding 501 of the current transformer 5 to one end 6 of the input terminal of the brifuge type ImIUlfi6 consisting of diodes 601 to 605.
0G, and one end of the secondary winding 202 is connected to the bridge type rectifier ff through the other primary winding 501 of the current transformer 5.
It is connected to the other input terminal 608 of 1ll+216. A negative output terminal 609 of the Blitzno type rectifier circuit 6 is connected to the cathode terminal IO, and a positive output terminal 607 is connected to the second collector terminal 11. A reset resistor 504 is connected in parallel to the secondary winding 503 of the current transformer 5, and further connected to a smoothing capacitor 506 and terminals 507, 508 via a diode 505. The secondary winding 202 of the transformer 2 is also connected to the input terminals 305 and 306 of the voltage doubler rectifier circuit 3.
04, the negative output terminal 308 of the single voltage rectifier circuit 3 is connected to the cathode terminal 10, and the positive output terminal 307 is connected to the first collector terminal 12. Furthermore, the secondary 4 wire 202 of transformer Co2 has 4 times the pressure! l style 1+!
It is also connected to input terminals 409 and 410 of circuit 4. 4 times voltage adjustment ft times 1234 is diode +101.403,4
06,407 and capacitors 402,404,405.4
It consists of 08. The negative output terminal 411 of the quadruple voltage rectifier circuit 4 is the cathode terminal 1
0, and the positive output terminal 412 is connected to ground via the power control circuit 8. Electricity! The 4-control circuit 8 is configured by connecting six field effect transistors 801 to 806 in series, and controls the potential between the cathode terminal 10 and the helix terminal 14. A series circuit of a power control circuit 7 and a resistor 712 is connected between the cathode terminal 10 and the power a control circuit 8,
Seven node terminals 13 are connected to these interconnection points. The power tsm circuit 7 includes ten field effect transistors 70
The field effect transistor 710 is insulated and driven by the optical coupling element 7!1. This power supply device configured as described above can obtain a voltage output of Class 4J4 C[current Ai] using a single high-14 wave source from the inverter 1 and using the cathode terminal IO as a standard. First, the cathode end? A voltage of 2 kV is generated between the IO and the second collector 11. Then, a voltage of 4 kV, which is twice the first collector voltage, is generated at the m1 collector terminal 12 with the cathode terminal 10 as a reference. Furthermore, a flIILiI'li voltage of about 7 kV is applied between the cathode terminal IO and the grounded terminal 14. Therefore, the potential of the cathode terminal IO is floatingly charged to -7 kV. A part of the potential of the cathode terminal 10 is divided by the power tq control circuit 7 and the resistor 712 into a part Ml 74
ill, and supplied to the anode terminal 13. Here, each current is expressed as follows, and the cathode current 1 is expressed by the following equation (2). Anode current: [a Cathode current: Ik Helix electric! :th First collector fa current: Icl Second collector current: 1c2 Ik= Icl + Ic2 + la+ Ih ・
・・・・・・・・・・・・・・・・・・・・・ΦHelix flow to cathode current 1 here! Since h is a negligibly small value compared to the first collector current 1cl and the second collector current 1c2, if these are ignored, the equation 0 is approximated as the following equation 0. To 1! +lIc1+lc2・・・・・・・・・・・・・
・・・・・・・・・・・・・・・・・・・・・・・・ ■Primary winding 50 of current transformer 5 when diode 505 becomes conductive
1 current 1501 is. +501= 1/2 ・Ic2 ・・・・・・・・・
・・・・・・・・・・・・・・・・・・・・・■Again. Primary winding 5 of current transformer 5 when diode 505 conducts
02 current 1502 is. +502= 1/2 ・Ic2 + lcl...
・・・・・・・・・・・・・・・・・・■ Therefore, the current flowing through the diode 505 ■ 505 is the turns ratio of each winding! given that. 1505=1501+1502=lcl+Ic2'+Ik ・・・・・・・・・・・・・・・・・・・・・・・・・・・
・・・・・・・・・・・・・・・・・・-0 Therefore, the current +505 flowing through the diode 505 is almost equal to the cathode current 1k, which is connected to the capacitor 506.
The terminals 507 and 508 are smoothed by the cathode voltage m.
A signal approximately equal to lk is generated. The diodes 604 and 605 of the bridge rectifier circuit 6 are connected in parallel with each other to generate a current field twice that of the other arms. It is. The current of the voltage doubler rectifier circuit 3 joins this arm, and +
Since twice as much current flows as in the arm No. 11, it has the optimum current capacity. (Effects of the Invention) The present invention has the features described above.
An AC current transformer functions as a tIL device. An AC current transformer has a simpler structure than a DC current transformer, and the 1fl
This is suitable when the battery is floatingly charged at the iffi pressure. Also, by combining the floating-charged rectifier circuit of the dish circuit as in the present invention, the capacitance of the diode of the high voltage rectifier circuit can be selected economically.
