A method of handling a peak power requirement of a medical imaging device 106 is presented. The method includes determining, using at least one controlling unit 107, 108, a first voltage corresponding to a direct current (DC) link 116, a second voltage corresponding to one or more energy storage devices 110, or a combination thereof, where a power source 102 is coupled to a plurality of loads via the DC link, and the energy storage devices are coupled to the DC link. Further, the method includes comparing, using the at least one controlling unit, the first voltage with a first reference value and the second voltage with a second reference value and regulating, using at least one controlling unit, at least one of the first voltage and the second voltage based on the comparison, to handle the peak power requirement of the medical imaging device.
