Customer Reviews
The converters corresponding to your INVOICE NO. HS2015021 work very well. We would like to order more

—— Peter

I'm very happy with your good communication skills as well as follow up and good deal. I will definitely inform you my further program for further coo

—— Vinay

We tested it and it worked.  I will let you know about future purchases soon.

—— Alvin

Thank you! It is a pleasure, to work with a company that wants to make it right for the customer :) many times i deal with Chinese companies that do not care about the customer and long term business. I think I made the right decision going with you and Altrasonic !!!

Introduction to the principle of ultrasonic generator
Latest company news about Introduction to the principle of ultrasonic generator

Ultrasonic generator, also known as ultrasonic drive power supply, electronic box, and ultrasonic controller, is an important part of the high-power ultrasonic system. The function of the ultrasonic generator is to convert the mains electricity into a high-frequency alternating current signal matched with the ultrasonic transducer to drive the ultrasonic transducer to work. High-power ultrasonic power supply generally adopts the circuit form of switching power supply from the aspect of conversion efficiency. Ultrasonic power supplies are divided into self-excited and other-excited power supplies. Self-excited power supplies are called ultrasonic analog power supplies, and other-excited power supplies are called ultrasonic generators.


The ultrasonic generator adopts the world's leading separately excited oscillation circuit structure, which increases the output power by more than 10% compared with the self-excited oscillation circuit structure. The form of ultrasonic amplifying circuit adopts linear amplifying circuit and switching power supply circuit.


The advantages of switching power supply circuit: high conversion efficiency, so high-power ultrasonic power supply adopts this form.


The advantages of linear power supply circuits: the circuit matching is not strictly required, and the operating frequency is allowed to change continuously and rapidly.




The ultrasonic generator can monitor the working frequency and power of the high-power ultrasonic system.

According to the different requirements of users, various parameters such as power, amplitude, running time, etc. can be adjusted in real time.

Frequency fine-tuning: Adjust the frequency to make the ultrasonic transducer always work in the best state, the efficiency reaches the maximum, the adjustment range is 2%.

Automatic frequency following: Once the device completes the initial settings, it can operate continuously without adjusting the generator.

Amplitude control: When the load changes during the working process of the transducer, the drive characteristics can be automatically adjusted to ensure a stable amplitude of the tool head.

System protection: When the system is working in an unsuitable operating environment, the generator will stop working and give an alarm to protect the equipment from damage.

Amplitude adjustment: The amplitude can be increased or decreased instantaneously during the working process, and the setting range of the amplitude: 0%~100%.

Automatic frequency search: The working frequency of the tool head can be automatically determined and stored.
