Which device converts alternating current to direct current in the x-ray system?

Rectification is the process that converts alternating current into direct current. In an x-ray system, the power supply provides high voltage AC, but the x-ray tube needs electrons moving toward the anode in one steady direction during exposure. A rectifier changes the current so the tube always sees the same polarity, giving consistent, reliable x-ray production. Modern units use silicon diode rectifiers for efficient DC; older systems used vacuum tubes or selenium rectifiers. The transformer alters voltage but remains AC, the control panel handles settings, and the x-ray tube is the load that uses the current.
