Abstract
An ultrasonic system for homogenizing a sample includes an ultrasonic transducer and a control system. The transducer includes a horn or other probe that oscillates to produce cavitation in the sample and a converter that drives the horn through its oscillatory motion. The control system includes a closed-loop amplitude-control configuration and process. In particular, the control system includes a user interface, a controller, and a high-frequency driver, all connected together in a closed-loop configuration for enabling amplitude-control feedback. Control software includes programming for the closed-loop amplitude-control process including receiving a user-inputted desired amplitude of oscillatory horn motion, driving the transducer at a corresponding power level, determining the actual amplitude of oscillatory horn motion, and automatically adjusting the power level to the transducer to maintain the desired amplitude during operation of the ultrasonic system.
