Abstract
An ultrasonic driver determines an optimal operating frequency for an ultrasonic transducer, and drives the transducer at its optimal frequency. A microcontroller controlling a MOSFET driver selectively alters the operating frequency of the transducer until a maximum operating current is detected by a transducer performance detector. The transducer performance detector provides an acknowledgment signal to the microcontroller upon detecting the maximum operating current, causing the microcontroller to lock the operating frequency at the current, optimal value.
