Control circuit for piezovalve used for automotive applications with regulating stage setting voltage at center node between series piezoactuators dependent on supply voltage and valve control signal
Control circuit for piezovalve used for automotive applications with regulating stage setting voltage at center node between series piezoactuators dependent on supply voltage and valve control signal
The control circuit has a regulating stage (20,22,24,28,32) for setting the voltage at a center node (18) between 2 piezoactuators (12,14) of the piezovalve (10), which are connected in series between a supply voltage and a reference potential, in dependence on the supply voltage and a valve control signal (34). Also included are Independent claims for the following: (a) a control method for a piezovalve; (b) a piezovalve.
