ABSTRACT:
A method and apparatus for high power pulse modulation which includes a high voltage supply to provide a high voltage input signal, and a drive channel, rise channel, fall channel, and dump channel. A timing system controls the switching of the drive channel, rise channel, fall channel, and dump channel to modulate the high voltage input signal to produce an output signal. Each channel comprises a channel logic input, buffer amplifier, alternating current (AC) coupler, isolation pulse transformer, current limiter, and switch to provide the pulse modulation. Power MOSFETs can be used as switches in the four channels.
