Claim 3:
4. A driver cell in a capacitive element driving circuit electrically connectable between a capacitive element and a voltage source arranged to supply a selected voltage to the capacitive element driving circuit, the capacitive element comprising an element having capacitive functionality, and the driver cell arranged to drive the capacitive element between two voltage levels, wherein the driver cell comprises:
a first input terminal electrically connectable directly or indirectly to a first terminal of the voltage source;
an output terminal electrically connectable directly or indirectly to an input terminal of the capacitive element;
a second input terminal electrically connectable directly or indirectly to a second terminal of the voltage source;
a plurality of switches further having
a first switch electrically connectable in series between the first input terminal of the driver cell and the output terminal of the driver cell, and
a second switch electrically connectable in series between the second input terminal of the driver cell and the output terminal of the driver cell; and

a plurality of non-dissipative element arranged to store and transfer energy for driving the capacitive element between the two voltage levels, wherein the plurality of non-dissipative elements is electrically connectable in parallel or in series:
at a first end between the first input terminal and the output terminal, and
at a second end between the second input terminal and the output terminal;

wherein the plurality of switches is arranged to open or close in combinations in a sequence of switching stages while maintaining an average voltage level value of the non-dissipative element unchanged over time, the 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.
