Anode voltage

from Wikipedia, the free encyclopedia

The anode voltage is the voltage that is applied between the anode and the cathode of an electron tube or picture tube . It is often in the range of 200-300 V and more, but there are also low-voltage tubes that already work with an anode voltage of around 6 V, and a high voltage in the range of a few kV for small oscilloscope tubes up to over 30 kV for large color television tubes is used for picture tubes . It forms in the tube a electric field from which the released by the Heizkathode electrons accelerated towards the anode.

In the early days of radio technology, the anode voltage was generated by an anode battery with a corresponding number of elements. Since voltage- proof rectifiers have been available, the (mains) voltage that is too low on the primary side is either transformed or directly multiplied and then rectified.
