<p>The invention relates to a device which makes it possible to obtain electrode biasing voltages for deflecting the electron beam emitted by a cathode of an X-ray tube. …<??>The invention lies in the fact that four DC voltages +/-V1 and +/-V2 are generated (30, 40) in order to apply them to a mixer circuit (55) in which they are added algebraically by diodes (D1 to D4) to floating-reference pulse voltages +/-V3 so as to obtain charging voltages VS1, VS2, VS'1, VS'2 for capacitors C15 and C14, such that:… VS1 = V3 - V1, VS2 = -V3 + V2… VS'1 = -V3 + V2, VS'2 = V3 - V1 …<IMAGE>… </p> |
