Circuit arrangement for controlling piezoelectric material e.g. for piezoactuators, has electronic element parallel to piezoelectric element in bridge circuit

摘要

A circuit arrangement for controlling piezoelectric material to obtain high voltage and a curved generation form comprises a voltage source, a coil with an electronic switch and a diode. A piezoelement (5) is in parallel with an electronic element in a given relation to the connections (A,B) An Independent claim is also included for use of the above to drive piezoelectric devices.
