(57) Abstract :
The invention relates to a switching device for an X-ray generator for providing a required output power voltage at an output of a
resonance power converter. The switching device may comprise a main switch 16 and an auxiliary switch 26 wherein the main
switch 16 may comprise a first internal capacitance 5 and wherein the auxiliary switch 26 may be connected in parallel to the main
switch 16. Moreover the main switch 16 may be controllable and the auxiliary switch 26 may be also controllable. Furthermore
the auxiliary switch 26 may be controllable in dependence of the main switch 16 wherein the auxiliary switch 26 may be
controllable for discharging of the first internal capacitance 5 of the main switch 16.
