Power generation system and package

An X-ray generation system comprising:

• a power source for providing a low-voltage alternating current an X-ray tube comprising an anode and a cathode;
• and
• a power generation system configured to convert the low-voltage alternating current from the power source into a high-voltage direct current supplied to the X-ray tube, the power generation system comprising a number N of voltage-conversion modules electrically connected in series, the voltage-conversion modules each comprising:
• a transformer coupled to the power source configured to convert the low-voltage alternating current into a high-voltage alternating current;
• and
• a multiplier configured to convert the high-voltage alternating current from the transformer into the high-voltage direct current, the multiplier comprising a positive multiplier part and a negative multiplier part, the positive multiplier part and the negative multiplier part each comprising a pair of input terminals connected in parallel with the transform and at least one multiplier stage comprising a single diode and a capacitor assembly.
