Claim Text:
1. A switching arrangement for applying voltage pulses across a load, comprising a plurality of capacitive elements connected in a series connection, a first switch arrangement for connecting one end of the series connection to one end of the load, a second switch arrangement for selectively connecting the other end of the series connection or a tapping between the ends of the series connection, to the other end of the load, in order to enable higher or lower voltage pulse levels to be applied across the load, and a control system to supply charging current through the series connection from one end, selectively to the other end or to the tapping, wherein the second switch arrangement comprises a pair of switches, with one switch of the pair being connected in a first path in series from the tapping to the other end of the series connection and a second switch of the pair being connected in a second path from the tapping in parallel with the first path, wherein the second switch arrangement is configured such that one of the switches in the pair of switches is controlled to be open and closed in opposition to the other of the switches in the pair of switches.
