ABSTRACT:
In a method and a device according to the present invention, two piezo-elements are driven with two voltages having a phase difference. One of the piezo-elements is charged by an inductive step-up means to a voltage exceeding an available power supply voltage. Subsequently charge, i.e. energy is transferred from the one piezo-element to the other piezo-element by an inductive element. The same inductive element is used in an inductive step-up means and in the transfer of the charge between the two piezo-elements.
