Abstract

A Russian power modulator, which is based on a diode that has been touted as a high-power solid-state pulsed power 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 a pulse of 150 kV amplitude and 25 ns half width into a 350 /spl Omega/ 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.
