Claim:
1. A plasma generating device for generating a plasma comprising: at least two plasma modules; a module housing provided to each plasma module, wherein the plasma module has at least one gas inlet for supplying a process gas; a piezoelectric transformer and a controllable electric driver module are provided in the module housing for generating the plasma from the process gas; a plasma outlet; and at least one gas outlet for a portion of the process gas is provided with each plasma module, wherein the at least one gas outlet of at least one plasma module opens in each case into the gas inlet of another plasma module; and the plasma modules are pluggable connected with each other in a form-fit and/or force-fit manner, wherein a spacing bridge has a connector and the at least one gas inlet and the at least one gas outlet, and the spacing bridge connects at least two successive plasma modules to each other such that the connector of the spacing bridge electrically connects the control modules of the plasma modules, and that at least one gas outlet of one plasma module is in fluid communication with the gas inlet of the spacing bridge and the gas outlet of the spacing bridge is in fluid communication with a gas inlet of a further plasma module, and wherein the plasma module and the spacing bridge are pluggably connected to each other so that a form-fitting and/or force-fitting connection is produced.
