Title: Design of Extreme High Voltage High Stability Test Voltage Source
Abstract: This paper designs an extreme high voltage and highstability test voltage source. First of all, the design of a highstability direct current(DC) voltage source is realized by using a high-frequency transformer and a two-stage boosting method of a voltage-doubling rectifier circuit. In this way, a voltage source with lower ripple factor and higher stability can be obtained. Then, in order to obtain a fast and free experimental platform, this paper designs an integrated voltage doubling and pressure measurement for the structure of the DC voltage source voltage equalization system, and effectively solves the problem of series voltage equalization of high-voltage silicon stacks. According to the scheme of this paper, the voltage source is designed, the output voltage is 1100kV, the ripple coefficient is 0.059%, and the stability is better than 0.05%/h. It reaches the domestic leading level which has been successfully applied to the DC voltage transformer of ±400kV sense converter station in Lhasa.
