Abstract
A high-frequency x-ray generator having low high-voltage ripple at the x-ray tube with a small amount stored energy in the high-voltage circuit and low drive frequency has a series of secondary windings each connected to a high-voltage rectifier having a capacitor connected in parallel. These capacitors are connected in series for forming the x-ray tube voltage. Each secondary winding has a primary winding allocated to it. The primary windings in combination with delay capacitors form a delay line in which a traveling wave is generated by a primary voltage source.
