ELECTRON GUN DRIVER Russian patent published in 2024 - IPC H05H7/02 H05H9/04 H01J29/96 H02M1/36 

FIELD: physics.

SUBSTANCE: invention relates to three-electrode electron gun drivers. Electron gun driver comprises a half-bridge driver circuit comprising an excitation circuit configured to generate an excitation voltage on the grid for outputting the electron gun grid and including: excitation voltage amplifier configured to provide excitation voltage on the grid for the driver half-bridge circuit, an excitation digital-to-analogue converter (DAC), made with possibility to generate programming voltage supplied to excitation voltage amplifier, and a drive voltage switch configured to apply drive voltage on the grid to the grid terminal; a cutoff circuit configured to generate a cutoff voltage on the grid for outputting the electron gun grid; a gate driver configured to switch between the drive voltage on the grid and the cutoff voltage on the grid; and an excitation controller configured to generate pulses supplied to the input of the excitation circuit and the cutoff circuit, and grid switching signals for the gate driver.

EFFECT: broader controllability of energy and pulse dose.
