Ultrasonic welding generator, also known as ultrasonic welding power supply, is an important part of high-power ultrasonic system. The role of the ultrasonic generator is to convert the mains power into a high-frequency alternating current signal that matches the ultrasonic transducer and drive the ultrasonic transducer to work. From the aspect of conversion efficiency, high-power ultrasonic power supply generally adopts the circuit form of switching power supply. Ultrasonic power is divided into self-excited and self-excited power. Self-excited power is called ultrasonic analog power, and it is called ultrasonic generator.

The ultrasonic generator adopts the world's leading separately-excited oscillator circuit structure, which has an output power increase of more than 10% compared with the self-excited oscillator circuit structure. Ultrasonic amplifier circuit uses linear amplifier circuit and switching power supply circuit.
The advantages of switching power supply circuits: high conversion efficiency, so high-power ultrasonic power supplies use this form.
Advantages of linear power supply circuits: circuit matching is not strictly required, allowing continuous and rapid changes in operating frequency.
The ultrasonic generator generates a specific frequency signal. This signal can be a sinusoidal signal or a pulse signal. This specific frequency is the frequency at which the transducer works. Ultrasonic equipment generally uses ultrasonic frequencies of 15Khz,20KHz, 25KHz, 28KHz, 35KHz, 40KHz, 60KHz, 70KHz, 100KHz .15Khz~70khz manily for ultrasonic welding system, 60Khz,100khz mainly for ultrasonic atomize ayatem.And also 20Khz ,28khz,40khz applied in ultrasonic liquid processing.
