It is configured to rectify high frequencies of 20kHz to 50kHz to make it compact and lightweight.

加する問題が生ずる。Desirable output characteristics of this type of DC high voltage generator require a small voltage fluctuation and a small ripple value. A small voltage fluctuation can be achieved by detecting the output voltage value and comparing it with the reference voltage, and using a high-gain negative feedback amplifier. On the other hand, for small ripple values (which can be achieved by increasing the capacity of the smoothing capacitor, it is an obstacle to downsizing). The most effective one is to keep the AC side arm of the multistage voltage doubler rectifier circuit away from the DC side arm. It is to arrange. However, it was difficult to solve under the condition of having multiple multi-stage voltage doubler rectifier circuits and making them compact. Further, the provision of the shield plate is effective for reducing the ripple voltage, but if a shield plate having a zero potential is present in the high voltage generator, the volume for insulation increases.

さくすることができる。[Operation] Since the push-up column is separated from the output terminal, the AC component of the push-up column voltage is not induced in the output. Therefore, the output ripple can be suppressed low. In addition, since the push-up column is isolated, the equivalent capacitance seen from the input side of the multistage voltage doubler rectifier circuit is reduced, and the reactive power of the AC source that drives this multistage voltage doubler rectifier circuit can be reduced.

い。In FIG. 2, on the left side of the anode output terminal 27, there are a capacitor group 19, a diode group 17, and a capacitor group 15.
Are sequentially arranged on the same plane. In the multistage voltage doubler rectifier circuit 18, the capacitor group 19 is called a so-called smoothing column, and a voltage with a large DC component is applied. On the other hand, the capacitor group 15 is a so-called push-up column, on which the alternating current component of the high frequency source 2 is superposed every half cycle. The capacitor group 15 applied including the voltage of this AC component is arranged away from other components. And a group of capacitors with many DC components
Since 17 is arranged near the anode output terminal 27,
The ripple applied to the anode output terminal 27 is small.
Similarly, to the right of the G3 output terminal 29, the capacitor group 21, the diode group 23, and the capacitor group 25 are arranged in this order substantially in the same plane. In the multistage voltage doubler rectifier circuit 24, the capacitor group 21 is a so-called smoothing column, and a voltage with a large DC component is applied. On the other hand, the capacitor group 25 is called a so-called push-up column, on which the alternating current component of the high frequency source 3 is superposed every half cycle. The capacitor group 25 applied including the voltage of this AC component is arranged away from other components, and the capacitor group 21 with many DC components is arranged near the G3 output terminal 29. The ripple applied to the output terminal 29 is small. The anode output terminal 27 and the G3 output terminal 29 are arranged adjacent to each other, but since the voltages applied to these terminals have small ripples, they do not act to increase each other.

全に対処できる。In FIGS. 1 and 2, the protective resistors that are actually required are connected in series to the Aroud output terminal 27 and the G3 output terminal 29, respectively. Further, resistors for detecting each output voltage are connected to the anode output terminal 29 and the G3 output terminal 29, but these resistors are omitted in FIGS. 1 and 2. In addition, the image intensifier tube requires a voltage in addition to the anode electrode and G3 electrode, but these voltages are relatively low, so it is easy to connect the necessary capacitors in parallel to reduce ripples. And can handle it safely.
