Abstract: An Ultrasonic oscillator driver with digital frequency sweep function is proposed in this paper.Ultrasonic transducers are widely utilized in various applications, such as liquid atomization.The drive circuit causes the ultrasonic transducer to vibrate, while the attached atomization component converts the liquid into fine particles.In this paper, the LC resonant circuit is adopted to drive the ultrasonic transducer.Due to small variations in the resonant frequency of each transducer, the optimal operating frequency also varies and may change as physical conditions change.Then, microcontroller units (MCU) are used to control circuit switches to achieve frequency adjustment, scanning and tracking, so that the ultrasonic oscillator works in the best state.
