Piezo Controllers / Mechanisms: How to Select the Right Piezo Controller / Driver
the piezo ceramic actuator. In our example, the required drive average current is 65mA and the peak current is 204mA. For pulse signals and other waveforms, these rules apply: Pulse operation is considered [...] considered when the duty cycle of the waveform is very low, i.e. the time between changes (idle time) >>10X of the actual rise / fall time (pulse width). Compare the required current and time (dt) with the [...] Corresponding Average Output Power In our example, we calculated the required average drive current as 65mA. Multiplied by the nominal drive voltage of the amplifier, the required power results, in this example
