Ultrasonic technology has been widely used in fields such as welding, cleaning, shearing, and medical treatment. As one of the cores of ultrasonic technology, the development of ultrasonic power and frequency control circuit boards has also undergone significant changes with the development of power electronics and digital control technology. However, currently, most ultrasonic power sources on the market are specialized ultrasonic power sources, and a power source can only be matched with a fixed transducer, It is not possible to achieve phase locking and frequency tracking in a wide frequency range. Starting from frequency tracking and impedance matching, this paper designs a variable frequency ultrasonic power supply. Through frequency tracking, impedance matching adjustment in a wide frequency range is achieved, and a prototype system is designed on the platform
