X-ray high voltage inverter frequency

What is X-ray HV generator?

A X-ray HV generator, which has output voltage from 60kV to 160kV and tube current from 1mA to 10mA, is developed successfully by applying the technology of LC series resonant soft-switching, high voltage doubling and rectifying, full bridge inverter and pulse width modulation.

Do X ray units need a high voltage generator?

X-ray units require a high voltage generator to supply necessary power in an x-ray tube. In order to control the speed at which the electrons travel and strike the anode, high-voltage/potential needs to be maintained between the cathode and the anode in the X-Ray tube .

How X ray tube is converted from low DC source?

The DC high voltage for X-ray tube was converted from the low DC source, provided by CT system, through inverting of high voltage inverter, boosting of transformer and multiplying and rectifying of high voltage doubling and rectifying circuit.

How X ray is generated by inverting a filament inverter?

circuit through inverting of filament inverter and dropping of transformer. X ray wit h certain dose for inspection would be generated by applying high vo ltage output and filament current to tube. Figure 1. Block diagram of integrated power source system. computer were achieved by control module.

Are high frequency generators better than conventional X-rays?

With High Frequency Generators the X-Ray procedure becomes much easier to use with less calculations involved allowing for a faster patient turn-arounds and return on investment. With lower power requirements from HF generators as compared conventional X-Rays the transformer and generator physical size also reduced.

Why do we use high frequency inverter circuit?

The high frequency inverter circuit was used to decrease the size of transf ormer, because of the limitation of m echanical structure size. That could a lso decrease the size of capacit ors used in rectifying and f iltering circuit. So, the inverter section was designed to full-bridge inverter st ructure, and IGBT was selected as switching tubes.
