Problems solved by technology

However, in the existing high-voltage amplifiers, the output voltage is applied to both ends of a single high-voltage optocoupler.
The output voltage range of electronics is limited by the withstand voltage value of a single high-voltage optocoupler. The difference between the upper and lower limits of the output voltage generally does not exceed 8kV, and it is difficult to further increase the output voltage range.
[0005] From the above, in the prior art, the electronic device for powering the electrodes of the plasma detector has a relatively small adjustment range for the output voltage

Description

technical field [0001] The present invention generally relates to the technical field of space environment detection load equipment, and in particular to a voltage amplifier device for space low-energy plasma detectors. Background technique [0002] Low-energy plasma generally refers to plasma with energy lower than 50keV. The low-energy plasma detector is installed on the spacecraft to detect the energy and flux of the space low-energy plasma at the location of the spacecraft during flight. The main components of the instrument include: electrostatic deflection system (deflection pole), energy analysis system (electrostatic analyzer), counting system (microchannel plate) and electronics system, etc. From the perspective of the flight path, the elevation angle of the ions or electrons in the plasma is sequentially measured by the electrostatic deflection system, the energy-to-charge ratio is measured by the energy analysis system, and finally the azimuth and flux are measur...
