PURPOSE:To simply constitute a circuit and simultaneously to well and efficiently drive a piezoelectric actuator by adjusting the frequency of a driving signal by using phase relation between the voltage and the current of the driving signal supplied to the piezoelectric actuator. CONSTITUTION:This circuit is constituted so as to adjust the frequency of the driving signal by using the phase relation between the voltage and the current of the driving signal supplied to the piezoelectric actuator 3. |
