この発明は、２つの異なる遅波回路電極電圧を
切換えて動作させるためのマイクロ波電子管用高
圧電源装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-voltage power supply device for a microwave electron tube that operates by switching between two different slow-wave circuit electrode voltages.
熱陰極、加速電極からなる電子銃と、遅波回路
電極と、集電極とから構成され、電子と電磁波と
の相互作用により電磁波を増幅するマイクロ波電
子管は一般に電子ビーム加速のため数千ボルトの
高電圧を必要とする。 Microwave electron tubes consist of an electron gun consisting of a hot cathode and an accelerating electrode, a slow-wave circuit electrode, and a collector electrode, and amplify electromagnetic waves through the interaction between electrons and electromagnetic waves. Generally, microwave electron tubes generate several thousand volts to accelerate the electron beam. Requires high voltage.
マイクロ波電子管の一種である進行波管は、そ
の増幅特性が広帯域である特徴を持つているので
よく使用される。 Traveling wave tubes, a type of microwave electron tube, are often used because of their wideband amplification characteristics.

させるには２つの遅波回路電極電圧を切換えて動
作させることにより可能であることがわかる。 Figure 1 shows the tendency of frequency characteristics using the slow wave circuit electrode voltage of the traveling wave tube as a parameter, and 1 indicates the bandwidth.
When the slow wave circuit electrode voltage is synchronized to approximately the center frequency 2 of 1 and 3 , 2 is when the slow wave circuit electrode voltage is synchronized to the higher frequency of the bandwidth,
3 is the opposite of characteristic 2, when the slow wave circuit electrode voltage is synchronized to the lower frequency of the bandwidth, 4 is the case where the bandwidth is roughly divided into two and the output is flattened in the low frequency band (between 1 and 2 ). When the slow wave circuit electrode voltage is set to give the best charge, 4' divides the bandwidth into approximately two parts, resulting in a high bandwidth (
2 to 3 ), the characteristics are shown when the slow wave circuit electrode voltage is set to provide the best flatness of the output. It can be seen from FIG. 1 that the traveling wave tube can be operated over a wider band and with better output uniformity by switching the two slow wave circuit electrode voltages.

欠点があつた。 FIG. 2 shows a circuit of a conventional high-voltage power supply device for obtaining flat characteristics. When the switch 11 is turned on, a high voltage determined by the primary and secondary turns ratio of the high voltage transformer 12 is generated, and the rectifying and smoothing circuits 13 and 1
4, 15, 16 through the collector electrode voltage, accelerating electrode voltage, and the first slow wave circuit electrode voltage between the cathode and terminal A.
Ehel 1 and a second slow wave circuit electrode voltage Ehel 2 are output between the cathode and terminal B, respectively. Switching between the two slow wave circuit electrode voltages is done using a switch 17 provided on the high voltage side.
However, when switching the switch 17, there is a moment when the switching contact is not connected to either terminal A or terminal B. The slow-wave circuit electrode voltage is not applied to the traveling-wave tube at this instant, and this causes an increase in the slow-wave circuit electrode current, which adversely affects the life of the traveling-wave tube, and the switch 17 must be operated frequently. In the worst case, this can lead to damage to the traveling wave tube. In addition, since a high voltage is applied to each terminal of the switch 17, a sufficient withstand voltage must be provided, resulting in the disadvantage that the entire power supply device becomes bulky and expensive.
