I'm attempting to drive an array of piezo transducers and am struggling to find a good design capable of driving from around +-5V to +-30V at about 2A for my testing. There are about 12 sets of transducers that will need to operate independently and thus require their own driving circuitry. I am planning to use half H-bridges for this. Something like this image:
I've got access to a 0-30V, 10A supply, but most of the circuits I've come across for split rail designs are a bit underpowered and intended for fixed voltages such as this one:
I also looked at using something like an LM1370 (500kHz High Efficiency 6A Switching Regulator), but it seems as though it may underpowered too.
I apologise if this question is a bit open-ended, but if anyone has any advice on an reasonable solution for this, I'd be very grateful.
Thanks in advance for any help!
