A switching arrangement for applying voltage pulses across a load, comprising a plurality of capacitive elements (C1-C9) connected in series, and a first switch arrangement (S) connected to the series connection to apply voltage pulses to the load, and a second switch arrangement (S1, S2) connected to a capacitive element of the series connection, such that one of the capacitive elements (C1) can be switched out of or switched into the series connection, in order to produce voltage pulses of respectively lower or higher levels, without the need to dissipate energy into a resistive load.
