Abstract:
A voltage generator for generating a high-frequency and high voltage signal for use in producing an electron beam, comprising:a boost transformer having first, second and third primary windings for receiving an AC supply voltage, and first, second and third secondary windings respectively associated with the first, second and third primary windings; a first input oscillation circuit coupled to the third primary winding and adapted to generate an input oscillating signal; a first output section coupled to the first secondary winding and adapted to generate an output signal having a DC voltage of at least one kV; and a second output section coupled to the second secondary winding and adapted to generate a pulsed signal having a peak to peak pulse width that is greater than the input oscillating signal; the outputs of the first output section, the second output section and the third secondary winding being coupled to each other to generate the high-frequency and high voltage signal.
