I have a piezo that has a resonant impedance of 2 ohms. I have an inductor in series that is matched for LC resonance. The piezo needs 200v, so how can i practically get the volts to 200? I have a drive board that supplies 14 amps and 50v. I currently get about 40v at 14A on the piezo at the resonant frequency. The capacitance of the piezo is 1.3uF and it resonates at 40KHz. Thanks, szzuk.
