I want to drive a piezo with this set up:
Amp : Transformer : piezo
Transformer is turns ratio 1:3
Piezo is capacitance of 1uF
piezo is operated at resonance of 100KHz
I'm currently designing the transformer I need to build but I'm finding I need a really low inductance on the primary coil. What should i do?
The calcs are these: Piezo capacitance refelected back to primary coil is 3uF. At 100KHz this implies I need a primary inductance of 0.8uH.
Thanks,
Szzuk.
