Modular power distribution unit for x-ray generation

A medical imaging system, comprising:

• an X-ray source configured to emit X-rays;
• a high voltage generator configured to provide power to the X-ray source;
• and
• a power distribution unit having a modular architecture and configured to receive electrical power from an electrical grid and to store the electrical power, wherein the power distribution unit is configured to regulate a high voltage direct current (DC) outputted to components of the medical imaging system including the high voltage generator, wherein the power distribution unit comprises:
• a motherboard mechanically supporting a plurality of mains bus bars, a plurality of DC bus bars, and a plurality of alternating current (AC) bus bars, wherein the plurality of main bus bars is configured to receive the electrical power from the electrical grid;
• one or more mains to DC boards electrically coupling the plurality of mains bus bars to the plurality of DC bus bars, wherein the one or more mains to DC boards are configured to absorb the electrical power from the plurality of mains bus bars, to convert the electrical power to DC power, and to provide the DC power to the plurality of DC bus bars;
• and
• one or more peak-power shaving boards electrically coupling an energy storage system to the plurality of DC bus bars, wherein the one or more peak-power shaving boards are configured to access stored DC energy from the energy storage system and to provide the stored DC energy to the plurality of DC bus bars when a power demand exceeds a programmed threshold.
