DuraAct Patch Transducer Power Requirements
To estimate the electrical requirements necessary for the operation of an actuator, the capacitance of the transducer plays an important role. The capacitance values of DuraAct patch transducers are typically in the nanofarad range and in each case are provided on the datasheets.
Here, the capacitance C is dependent on the type, thickness and area of the piezo ceramic used. To estimate the average electrical output Pm, the control frequency as well as the capacitance of the transducer and the voltage swing are required.
Pm = C · f · Uh2
f: frequency, Uh: voltage swing
The maximum power requirement Pmax can be calculated by multiplying the average electrical output by pi (π):
Pmax = Pm ・ π
