x-ray generators


an x-ray generators is device that supplies electric power to the x-ray tube


it begins with a source of electricity 220 or 380 volts alternating current 50 - 60 hertz and it modifies this
energy to meet the needs of x-ray tube
220 380 50 60


x-ray generators is contained in to two separate
components


control penal it contains main switch to turn on the machine three selector controls tow meters and tow exposure buttons
..

a metal box filled with oil it contains a step-up transformer high tension transformer a step- down transformer filament transformer and group of rectifiers
.. ( )

high tension transformer H.T.T


functions of H.T.T


is to transform voltage of mains supply up to thousads of required to operate x-ray tube it provides of kilovolts 20 - 150 kv

20 150

high tension transformer H.T.T supplies x-ray tube with an alternating kv


we have to change alternating current to unidirectonal current the process applied to achieve this aim is known as rectification


self rectified unets
