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 [...] 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 [...] stage capacitance of 3.1µF). For 6.2µF at 102.6V, the frequency axis shows ~115Hz; multiplied by 2, 230Hz results, which is significantly above the required 100Hz. E-754: Operating limits (open loop) with
