Abstract

A Russian Power Modulator, which is based on a diode that has been touted as a high power solid state opening switch (SOS) was characterized and tested. The diode has characteristics similar to those of a step-recovery diode, except that the reverse current density is 10-100 times larger than in US manufactured diodes. The modulator has a DC input voltage of 600 V and produces pulse of 150 kV amplitude and 25 ns half width into a 350 Ω load. The maximum pulse repetition rate is 100 Hz. The limit is given by thermal limitations and can be increased through the use of more effective cooling methods. The pumping system for this modulator uses ferrite cores in the magnetic circuit to minimize losses at high transition frequencies. Measurements of the output voltage, current, power and energy transfer efficiency have been made. In addition, the basic pulse forming circuit was separately build, tested and modeled.
