A solid state high voltage pulser for RADAR transmitter using fractional turn transformer

This work is concerned with the design and construction of a solid-state high voltage pulsed modulator for RADAR transmitter. The design parameters are chosen such that the pulse can be connected to the solid-state switch, which drives a segment of pulse transformer, no Pulse Forming Network (PFN) is required. The width of the pulse can be adjusted by simply adjusting the trigger duration of the solid-state switch and no PFN ripple occurs on the pulse. A new generation of solid-state high voltage modulators with performance rivaling that of hard tube modulator and thyratron switched line-type modulators is designed and tested for mobile application. The new solid-state switching devices offer the promise of high power efficiency and longer lifetime. Modern radar is based upon the generation of short pulses of electromagnetic radiation. The function of the pulser is to deliver high power in short pulses to a high frequency generator.
