Abstract

Power modulators have been designed which can generate fast rising, high voltage pulses up to 10 kV with arbitrary pulse widths at pulse repetition frequencies greater than 5 kHz. The design utilizes series IGBT switching. The modulators drive the NRL Agile Mirror experiment-an electronically steered sheet plasma which can be used to direct a microwave beam for radar and communications applications
