Claim 0:
1. An electroporation apparatus comprising:
a plurality of electroporation probe terminals;
a transformer for providing stepped-up voltage,
a switching circuit with switches for linking high voltage and low voltage or ground levels to the probe terminals; and
a controller configured to control said switches according to a control scheme to deliver pulses to the probe terminals, and in which said pulses are delivered to groups of at least two probe electrode terminals for probe electrodes which are spaced apart, and
wherein the controller is configured to apply a ramp-up (tr) duration of less than 0.5 μs to a plateau amplitude in the range of 100V to 3000V for a duration in the range of 1 μs to 5 μs, and a ramp-down (tf) duration from said voltage of less than 0.5 μs for each probe electrode terminal.
