Compact topology for adjustable highvoltage pulse generation with drift step recovery diodes

摘要

The introduction by the Ioffe Institute of an unconventional switching mechanism, based on the very fast recovery of a drift-step recovery diode (DSRD) allows methods for pulsed power generation [1–2]. Therefore a circuit topology is needed to generate a fast forward current through the DSRD, before a reverse current can activate the drift step recovery. This requires a complicated circuit, consisting of two well-tuned C-L-C circuits, with saturable inductor [3]. Adjustment of the high-voltage pulse amplitude is not possible with such a circuit.
