I want to test 2 different types of piezo actor.
For the one i need a voltage of -45V/125V for the others i need a voltage of -100/350V.
to switch the piezo between the negative and positive voltage levels i think the best solution is to use a h-bridge.
Did somebody have a useful design for the inverter and for the h-bridge?
what can i do that the hbridge switch correct for the negative voltage?
sorry for my bad english -- any help would be usefull.
many thanks
