Three high voltage modulators used during testing and operation ofthe Tevatron Electron Lens (TEL) at Fermilab will be described. Shorthigh voltage (0 to ~20 kV) pulses from these modulators vary theanode-cathode voltage of the TEL electron gun to control the magnitudeof the electron beam current. The trio of modulators include a lowrepetition rate MOSFET-based pulser, a fast ionization device, and ahigh average power tetrode modulator. The characteristics of each devicewill be discussed and typical outputs from each type of modulator willbe shown
