Claim 9:
10. A process for driving a capacitive element between two voltage levels, the process comprising:
electrically connecting a first voltage-receiving connection of a first capacitive element driver directly or indirectly to a first terminal of a voltage source;
electrically connecting a voltage-outputting connection of the first capacitive element driver directly or indirectly to an input terminal of the capacitive element;
electrically connecting a second voltage-receiving connection of the first capacitive element driver directly or indirectly to a second terminal of the voltage source; and
storing energy in a plurality of non-dissipative elements of the first capacitive element driver, the plurality of non-dissipative elements electrically connectable in parallel or in series:
at a first end between the first voltage-receiving connection and the voltage-outputting connection, and
at a second end between the second voltage-receiving connection and the voltage-outputting connection, and

operating the first capacitive element driver through a first sequence of switching stages, wherein the first sequence is arranged:
to transfer the energy in a first set of voltage steps 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
to cause a change in an output voltage of the capacitive element driver during application on the capacitive element driver of a voltage change portion of a switching pattern in the first sequence.
