What type of current is supplied in a commercial power supply to the x-ray circuit?

In a commercial power supply for an x-ray circuit, alternating current (AC) is typically supplied. This is because the electrical power grid delivers AC, which is the standard form of electricity used for most household and commercial applications.

X-ray machines often require a sophisticated high-voltage transformer to increase the voltage from the commercial power supply. This transformer operates on AC, allowing for efficient conversion to the high voltages needed for x-ray generation. Once the current reaches the x-ray tube, it may be converted to direct current (DC) for the operation of certain components within the x-ray system.

It's important to note that while the x-ray tube eventually needs a controlled and stable current, the initial power source comes as AC. This is advantageous because AC can be transformed easily to various voltage levels, providing the necessary input for the subsequent circuitry within the x-ray system.
