Title:
HIGH-VOLTAGE AMPLIFIER, HIGH-VOLTAGE POWER SUPPLY, AND MASS SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2019/187431
Kind Code:
A1
Abstract:
A positive high voltage, a first terminal of a semiconductor element, and a first terminal of a first resistance element are connected to a first terminal of a first current controller. A current input terminal of a first active element is connected to a second terminal of the first current controller, and a second terminal of the semiconductor element and a second terminal of the first resistance element are connected to a control terminal of the first active element. A second resistance element is connected between a current output terminal and a control terminal of the first active element. The first current controller allows a drive current corresponding to an input signal to flow in the first active element and allows the drive current output from the first active element to flow into a load, thereby generating an output voltage.
