Inductor testing frequency
<< < (3/3)
pete_dl:
Thank you for your detailed notes.

So if my actuation frequency was not so low, the reactive power could be recycled into the class D amp.

I need to drive multiple Piezoelectric actuators simultaneously. I am thinking I could recover half the energy by driving them in pairs. While one actuator is at Vmax, the other is at 0V. You PWM between them to get a sinusoidal change in voltage until both actuators are at Vmax/2, then push the pair to the whole voltage swing using the power supply. Could that work ?

Pete.

You can connect them in parallel, and bias one differently from the other, sure.

That doesn't automatically recover power, power is only about the change.
