| Abstract(in English) | Authors already have porposed the resonance frequency control method of piezoelectric devices using a Generalized Impdance Converter(GIC) circuit in order to change the reonance frequency continuously. The GIC circuit achieves a simulation inductance instaed of a solid coil element. As a result, it is found that the resonance frequeny can decent, comparing to the resonance frequency in the short condition of a controling port. In the practical use, the upward control of a resonance frequnecy is also requeired. Then, the simulation variable capacitance is realized by the modified GIC circuit. As a result, it is confirmed that the resonance frequency ascents using the simulation variable capacitance. Moreover, the simulation variable capacitance circuit in the combination of the solid inductance can provide both the varibale capacitance and the inductance. Applying this circuit to the bolt-clamped Langevin transducer, it is indicated that the resonance frequency will be able to rise and drop continuously. |
