Compact topology for adjustable high-voltage pulse generation with drift step recovery diodes

In this paper we present a circuit topology with driftstep recovery diodes. We will explore the effect of higher forward and reverse currents on the circuit performance. In addition, we realized an adjustable output voltage of the pulser. The primary capacitor voltage can be varied while maintaining proper saturation of the pulse transformer. We will introduce a solution with a pre-magnetizing circuit on the primary winding so that a third winding is not needed.
