200V from a 3V battery?
(OP)
I have been asked to investigate the possibility of generating a large voltage from a 3V battery. The specifications are vague at the moment but for now the range may be anywhere from 50 to 200V (single or dual supply). This is for a portable piezo driving application. Aside from charge pumps and DC/DC converters, I am somewhat at a loss on how this might be accomplished. Any leads to follow would be much appreciated!

Another technology is piezo 'transformers' where a small voltage makes the crystal vibrate, and the vibrating crystal is used to make a higher voltage on another set of terminals.

Due to the high current, the losses will be high.

Zetex transistors have some App Notes for simple and efficient inverter designs using ZTX8__ transistors.
I just 'googled' "zetex emergency inverter" and found a circuit in which you may be interested.
