High voltage power supplies (HVPS) in the range 100 to 200 kV are used for working with X-ray tube. Some HVPS produce negative output voltage or even bipolar output including negative and positive voltage. I want to know which type of HVPS is proper for X-ray tube; negative voltage, positive voltage or the bipolar one?

    \$\begingroup\$ There is no right or wrong answer but bipolar reduces the potential difference from ground that you have to deal with. \$\endgroup\$ Jun 10 '20 at 13:42

    \$\begingroup\$ Depends on tube type. Bypolar, and negative are usually used... Never positive, due to the want to have a gounded enclosure... \$\endgroup\$
