A modulator includes: a high voltage transformer transforming a voltage supplied through a primary side and a secondary side to apply a current pulse to a driving device; a bipolar pulse generator applying a magnetizing pulse and a main pulse to a connection line connected to the primary side of the high voltage transformer; and a timing controller controlling a time difference of applying the magnetizing pulse and the main pulse, wherein the bipolar pulse generator includes a magnetizing pulse generation unit generating the magnetizing pulse by using positive power, and a main pulse generation unit generating a negative pulse by using negative power. Also, the modulator includes a pulse waveform controller in which a plurality of unit modules of the same structure is disposed in series through a small transformer on the secondary side of the high voltage transformer. These two configurations may independently control the magnitude and the waveform of the current pulse of the high voltage, respectively and realize simultaneously two functions.
