A fast voltage ramp generator comprises a chain of transistors connected collector to emitter in series, and biased to avalanched switching mode. A respective transformer secondary is connected to apply a switching pulse across the base emitter junction of each transistor of the chain, to effect avalanche switching of the chain. The transformer secondaries are the secondaries of discrete transformers with respective primaries connected in series. The transformers are formed of ferrite beads having plated through holes constituting the secondaries of the transformers. The beads are threaded on an insulated conductor which constitutes the series connected primaries of the transformers.
