Various systems are provided for a power supply system. In one example, the system includes a power distribution unit configured to receive power from a main power source and an uninterruptible power supply (UPS), wherein the UPS is configured to directly power an output AC load, the UPS is further configured to power an output DC load after coupled through one or more transformers.

Provided is a radiation irradiation device that can improve the degree of freedom of an arm part and can reduce the number of noise suppression components, such as a ferrite core. A radiation irradiation device includes a radiation generating part having a radiation source that generates radiation; an arm part having the radiation generating part attached to one end thereof; and a main body part having the other end of the arm part connected thereto. The main body part has a power source part including a three-phase inverter circuit. The power source part supplies a three-phase alternating current voltage to the radiation generating part via the arm part.

A high voltage generator including a Cockcroft-Walton circuit structured to receive alternating-current power supplied from an alternating-current power source and apply a potential difference to a load includes: three or more circuit boards arranged at intervals in a thickness direction thereof; capacitors, each of which is shaped flat and mounted to a corresponding one of the circuit boards; and diodes, each of which is connected to corresponding ones of the circuit boards. Out of the three or more circuit boards, each circuit board other than two circuit boards disposed at both ends of the arrangement of the three or more circuit boards includes indentations. Each of the diodes is disposed in a corresponding one of the indentations.

A raster scanning x-ray source can be light and small, and can have high resolution. A raster-assembly can be attached directly to and can encircle an x-ray tube. The raster-assembly can adjoin or can be very close to the x-ray tube, resulting in a small and lightweight scanning x-ray source. X-rays can backscatter back into the x-ray tube instead of into a detector, thus improving resolution of the resulting image. A voltage-multiplier, which can be used with the x-ray source, can include separate voltage-multiplier-stages in a stack.

A system for providing electrical power to a load is provided. The system includes at least two inverters and at least two resonant circuits. The inverters are operative to electrically connect to a power source. The resonant circuits are each electrically connected to at least one of the inverters and operative to provide electrical power to the load. The resonant circuits are coupled to each other.
