A portable x-ray system includes an x-ray source, an internal power supply for supplying an input voltage, and a voltage converter in electrical connection between the power supply and the source. The converter varies the input voltage from the power supply to provide an output voltage useable in the x-ray source to generate x-rays of a predetermined energy. The power supply includes a battery power store, a capacitor power store, and a switching unit to selectively connect the power stores to the voltage converter individually or together to provide the input voltage to the voltage converter during an exposure.
