Designing nanosecond high voltage pulse generatorsusing power MOSFETs

Power MOSFETs in series are used for generating high voltage, >1 kV, pulses with nanosecond rise and fall times. The design procedures for series operation and driving power MOSFETs to attain nanosecond switching times are given. A –1500 V pulse generator is designed with a 3 ns falltime and a 15 ns risetime into a 50 Ω load.
