“…It is a kind of pulse power switch based on the plasma principle, which can operate in the inductive energy storage circuit. The DSRD-based pulse generator is widely used in ground penetrating radar [ 2 ], electromagnetic pulse radar [ 3 , 4 ], accelerator [ 5 ], igniter [ 6 ], ultra-high speed broadband beam deflection [ 7 ], etc. In order to improve its operating voltage and current and switching speed, DSRDs based on new materials such as silicon carbide (SiC) and gallium arsenide (GaAs) were prepared.…”

Silicon carbide (SiC) drift step recovery diode (DSRD) is a kind of opening-type pulsed power device with wide bandgap material. The super junction (SJ) structure is introduced in the SiC DSRD for the first time in this paper, in order to increase the hardness of the recovery process, and improve the blocking capability at the same time. The device model of the SJ SiC DSRD is established and its breakdown principle is verified. The effects of various structure parameters including the concentration, the thickness, and the width of the SJ layer on the electrical characteristics of the SJ SiC DSRD are discussed. The characteristics of the SJ SiC DSRD and the conventional SiC DSRD are compared. The results show that the breakdown voltage of the SJ SiC DSRD is 28% higher than that of the conventional SiC DSRD, and the dv/dt output by the circuit based on SJ SiC DSRD is 31% higher than that of conventional SiC DSRD. It is verified that the SJ SiC DSRD can achieve higher voltage, higher cut-off current and harder recovery characteristics than the conventional SiC DSRD, so as to output a higher dv/dt voltage on the load.

A solid-state modulator is being developed at the SLAC National Accelerator Laboratory for ultra-fast broadband beam deflection. The modulator design is based on an opening switch topology that uses Drift Step Recovery Diodes (DSRDs) as the opening switches. The modulator provides nano-second length pulses into a 50 Ω load, i.e. a strip line kicker. The rise and fall time of the kicker is primarily determined by the switching characteristic of the DSRD and has been measured as approximately 1.5ns with a 5kV output voltage. A pumping circuit for the DSRD kicker has been developed to drive 200A through the DSRD with a 3MHz repetition rate.
