Apparatus and method for driving capacitive load, and processing program embodied in a recording medium for driving capacitive load

摘要

A capacitive-load drive apparatus is provided with a first oscillation-transition-voltage-generation device which is connected between a first power supply and a capacitive load; a second oscillation-transition-voltage-generation device which is connected between a second power supply and the capacitive load; and a voltage-fluctuation-detection device which outputs a detection signal when the voltage of the first power supply or the second power supply fluctuates outside a specified range; and wherein the first oscillation-transition-voltage-generation device is provided with a first switch device and first inductance and moves the voltage of the capacitive load between a reference voltage and a first voltage by oscillation of the first inductance and the capacitive load; and the second oscillation-transition-voltage-generation device is provided with a second switch device and second inductance and moves the voltage of the capacitive load between the first voltage and a second voltage by oscillation of the second inductance and the capacitive load.
