Abstract:
    A high voltage power supply (HVPS) with digital control and a method of generating high voltage. The HVPS may include switching units to intermit a current flowing in a primary side coil of a transformer and to control a voltage induced into a secondary side coil of the transformer, digital control units to control the intermission of the switching units in response to an input control data, and a digital interface unit to provide the digital control units with the control data extracted from a control code that is transferred according to a predetermined communication protocol. Because the number of parts used for the HVPS is reduced, a printed circuit board space is used more efficiently and an overall process yield is increased.
