Process and device for controlling an electronic unit especially a piezoelectric ink jet printing head

摘要

The control device includes a variable voltage generator (13) connected to the input of a switching unit (5) having outputs (6) connected to electrodes (4) of an electronic unit (1), the switching unit (5) having an input (11) connected to a switching sequence generator (10) providing control of the switching unit so as at each instant to deliver the variable voltage selectively to some of the control electrodes. <IMAGE>
