Claim 6:
7. A capacitive element driver for driving a capacitive element between two voltage levels, the capacitive element comprising an element having capacitive functionality, and the capacitive element driver comprising a first circuit having:
a first circuit first voltage-receiving connection electrically connectable directly or indirectly to a first terminal of a voltage source for receiving the selected voltage from the voltage source;
a first circuit voltage-outputting connection electrically connectable directly or indirectly to an input terminal of the capacitive element;
a first circuit second voltage-receiving connection electrically connectable directly or indirectly to a second terminal of the voltage source; and
a plurality of first circuit non-dissipative elements arranged to store and transfer energy for driving the capacitive element between the two voltage levels, wherein the plurality of first circuit non-dissipative elements is electrically connectable in parallel or in series:
at a first end between the first circuit first voltage-receiving connection and the first circuit voltage-outputting connection, and
at a second end between the first circuit second voltage-receiving connection and the first circuit voltage-outputting connection;

wherein the first circuit is arranged to step-wise transfer energy directly or indirectly to the capacitive element from a first high voltage level to a first low voltage level or from the first low voltage level to the first high voltage level; and
wherein the first circuit is arranged to perform the step-wise transfer through operation of a first sequence of switching stages on the first circuit non-dissipative element, the first sequence of switching stages further comprising a switching pattern having a voltage change portion arranged to cause a change in an output voltage of the capacitive element driver during application thereof on the capacitive element driver.
