Ultrasonic power supply, also known as ultrasonic power source, is a device used to generate and provide ultrasonic energy to ultrasonic transducers. Ultrasonic energy converter is a device that converts electrical energy into mechanical energy. Its parameters directly determine the performance of Ultrasonic cleaning. This chapter mainly studies the principle of ultrasonic power supply system, discusses the commonly used topological structures of ultrasonic power supply, and determines the main circuit scheme of ultrasonic power supply.

Transformer; The inverter uses power semiconductor devices (IGBTs) as switching devices to convert direct current into the required high-frequency alternating current; By applying a matching network to the transducer load, the circuit is placed in a resonant state. Collect the current and voltage signals of the resonant circuit, and obtain feedback signals suitable for DSP processing through a feedback network; The signal processing circuit achieves frequency tracking and power regulation functions; The output signal of UC3875 is input into the high-frequency driving circuit as the driving and control signal of the power transistor IGBT.
