Device and control circuit for a piezoelectric actuator |
摘要 |
The piezoelectric ceramic driver command has a piezoelectric load circuit driven by a voltage converter to a continuous current feed at low voltage. The discharge circuit has an inductance (L) providing an oscillating circuit with the input voltage equal to that of the converter (11) and using a switch (T2) with a series diode (D2) passing the current in the discharge direction.
