摘要
As a new driving technology, piezoelectric driving has many considerable advantages and has brought widely-attention. But the application is limited because of its lower efficiency and its non-linearity capacitive vibrator. To improve its efficiency by matching between ultrasonic vibrator and its driving circuit, matching principle with a series-inductance was discussed in some papers, but how to settle the value of series-inductance was unknown. The effects of the series-inductance were simulated and discussed in this paper. Smallest phase matching theory was proposed and good experiments performance was achieved. The theory also applies to dynamic matching technique of piezoelectric vibrators.
