Description

[0002] A DC high-voltage generator is an electronic device used to generate high voltage and is widely used in the fields of electricity, electronics, communications, and medical treatment. During long-term use, the DC high-voltage generator requires regular maintenance to ensure its normal operation and extend its service life.
