Abstract
A power supply apparatus for supplying predetermined supply voltages respectively to an anode electrode, a cathode electrode, a collector electrode, and a helix of an electron tube. The power supply apparatus comprises an anode switch for turning on/off the anode voltage output, and an anode switch control circuit for controlling the on/off operation of the anode switch such that a pulsed anode voltage is repeatedly applied to the anode electrode a plurality of times at a predetermined period when operation of a helix power supply and a collector power supply is stopped.
Claims5
A power supply apparatus for supplying predetermined voltages respectively to an anode electrode, a cathode electrode, a collector electrode, and a helix contained in an electron tube, said apparatus comprising:
- an anode switch for turning on or off an anode voltage output which is a supply voltage fed between said cathode electrode and said anode electrode;
- and
- an anode switch control circuit for controlling an on/off operation of said anode switch such that the pulsed anode voltage is repeatedly applied a plurality of times at a predetermined period when the operation of a helix power supply, for supplying a helix voltage which is a supply voltage between said cathode electrode and said helix, is stopped, and when the operation of a collector power supply, for supplying a collector voltage which is a supply voltage between said cathode electrode and said collector electrode, is stopped.
