Abstract:
1. High-voltage AC-DC converter for converting alternating current ( 1 - 3 ) into high-voltage direct current to be provided to a load ( 12 ), said converter comprising at least one transformer ( 10 ), having at least one primary winding ( 18 , 22 - 25 ) on an AC-side and at least eight secondary windings ( 27 ) on a DC-side, the converter further comprising at least one rectifier ( 6 ) rectifying alternating input current, comprising at least one transistor bridge ( 8 ) for converting the resulting direct current into alternating current, said at least one transformer ( 10 ) transforming the resulting alternating current, and comprising at least eight high-voltage rectifiers ( 11 , 29 ) with one of the high-voltage rectifiers ( 11 , 29 ) connected to each of the secondary windings ( 27 ), wherein the output voltage of the high-voltage rectifiers ( 11 , 29 ) is connected in series, and each of the secondary windings ( 27 ) has an individual magnetic core ( 30 ).
