Method and configuration for driving a capacitive actuator |
摘要 |
In a driving configuration for driving an actuator, component tolerances are compensated for by measuring a discharging current flowing in a measuring branch and the discharging voltage during a charge-transfer (reversing) operation. The measuring branch contains a series resonance circuit having a charging capacitor, a coil, an auxiliary switch and a measuring resistor. The current and voltage values measured at various instants are evaluated; and from them, initial parameters are determined for the subsequent driving operations.
