Prototype Design of the High-Voltage Power Supply Module for an Electrostatic Analyzer in a Space Plasma Environment

In this study, the prototype of a sweep high voltage supply module for an electrostatic deflection system in an electrostatic analyzer. High-voltage optical coupler is used as the amplifying element for the sweep high-voltage supply, and the single push-pull amplifier composed of a single high-voltage optical coupler is used for the output. The experimental results reveal that the sweep high voltage supply could output positive voltage from the same output port, with the output voltage 0V - +3.5 KV, to satisfy the demand of the electrostatic deflection system for voltage supply. The voltage regulation speed is extremely fast. The stabilization time of the sweep high voltage supply module does not exceed 30ms to accelerate the sweep speed of the electrostatic analyzer and enhance temporal resolution. The integral nonlinearity (INL) of the sweep high voltage supply module is less than 13% and the prototype design satisfies the expected performance of the sweep high voltage supply module of the electrostatic deflection system.
