An N-transistor switches a current of a first constant current source by a positive input pulse to generate an output pulse current where an overshoot and an undershoot appear. A P-transistor switches a current of a second constant current source by a negative correction pulse applied at timing of occurrence of the overshoot to generate a correction pulse current. Another N-transistor switches a current of a third constant current source by a positive correction pulse applied at timing of occurr...

For several years, there has been interest in obtaining fast-rising, high-voltage pulses to drive particle-beam diodes and antennas in mobile situations. The Magnetic Voltage-Pulser (MVP) is a new device to satisfy this interest. The regime of operation of the basic unit comprises--output voltage=0.2 to 1.0 MV, pulse duration=1 microsec, and load impedance=1 to 10 ohms. For higher voltage and higher impedance needs, a plurality of pulsers can be used in a series-parallel arrangement. Typical dim...

A solid-state pulse generator using a split magnetic core transformer is described. In one embodiment, the solid-state drive circuit uses MOSFETs switching a blumlein to produce a desired input pulses in a primary winding of the split magnetic core. The pulse length is determined primarily by the characteristics of the blumlein and the split core transformer. The "on" time of the solid-state devices can exceed the output pulse length, thereby reducing the chance of damaging voltage spikes. The u...
