The Power Adjust Ultrasonic Generator is divided into a self-excited power source and an excitation power source. The self-excited power source is called an ultrasonic analog power source, and the excitation power source is called an ultrasonic generator.
Power Adjust Ultrasonic Generator, also known as ultrasonic drive power supplies, electronic boxes, and ultrasonic controllers, are important components of high-power ultrasound systems. The function of the ultrasonic generator is to convert the commercial power into a high-frequency alternating current signal matched with the ultrasonic transducer, and drive the ultrasonic transducer to work.

The ultrasonic generator produces a sinusoidal or pulsed signal of a specific frequency, which is the transducer operating frequency. The ultrasonic frequencies used in the ultrasonic device are 20 KHz, 25 KHz, 28 KHz, 33 KHz, 40 KHz, 60 KHz, and 100 KHz or more.
The amplifying circuit form adopts a linear amplifying circuit and a switching power supply circuit.
Advantages of the switching power supply circuit: The conversion efficiency is high, so the high-power ultrasonic power supply adopts this form.
Advantages of linear power circuits: Circuit matching is not strictly required, allowing the operating frequency to change continuously and rapidly.
The ultrasonic generator has a feedback link, which mainly provides feedback signals in two aspects:
The first is to provide an output power signal.
The second is to provide a frequency tracking signal.
The difference between Power Adjust Ultrasonic Generator and analog power supply:
Auto-following: Once the device has been initially set up, it can be operated continuously without the need to adjust the generator.
Automatic amplitude control: When the load changes during the operation of the transducer, the drive characteristics can be automatically adjusted to ensure a stable amplitude of the tool head.
System protection: When the system works in an unsuitable operating environment, the generator will stop working and display an alarm to protect the device from damage.
Amplitude adjustment: The amplitude can be increased or decreased instantaneously during the working process, and the amplitude setting range is 0%~100%.
Automatic frequency search: The working frequency of the tool head can be automatically determined and stored.
Overheat protection: It can protect the Power Adjust Ultrasonic Generator from damage.
