SOLID STATE ACTUATOR DRIVE DEVICE WITH ENERGY BASED CLOCKED FINAL POWER STAGE AND METHOD FOR CONTROLLING SAID TYPE OF FINAL POWER STAGE

摘要

The invention relates to an energy based clocked final stage of power for a solid body actuator-drive device (0), comprising one or several solid body actuators (3) and a control device (6) which is used to charge energy (Wcharge(i)) in the solid body actuator(s) (3) and to discharge energy (Wdischarge(i)) from the solid body actuator(s) (3). The control device (6) is embodied or provided in order to determined a charge value (Pmech(t)) and/or a temperature, which acts upon one of the solid body actuator(s) (3). The invention also relates to a method which controls the control device (6) which corresponds to the final stage of the power.
