ABSTRACT:
A method for stably driving a piezoelectric actuator includes the steps of applying a pulse voltage for a maximum of 100 ms per cycle. The piezoelectric actuator is driven for extended periods of time with little deterioration in its performance characteristics so long as the duty ratio DR of the voltage pulse during one cycle is given by:
