We have a problem when trying to drive a piezo transducer(the output of microcontroller is a 3.3V pulse, but the piezo works around 100V-300V, so we have to convert the 3.3V pulse to 100V pulse).

Does anyone has any idea about how to design the circuit? And how to design the protection circuit between the 100V drive voltage and the small voltage received by the transducer?
