Principle of Ultrasonic Generator
Ultrasonic generator is an important part of high-power ultrasound 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. The ultrasonic generator can generate a signal of a specific frequency. This signal can be a sinusoidal AC pulse signal. This specific frequency follows the working frequency of the transducer, so that the transducer always works at the resonance frequency.
Advantages of ultrasonic generators
1.The ultrasonic generator can monitor the working frequency, amplitude and power of the high-power ultrasonic system;
2. Able to adjust various parameters in real time according to different requirements of users: such as amplitude, power, running time, etc.;
3. Frequency fine-tuning: adjust the generator frequency to be closer to the transducer frequency;
4. Drive characteristics: meet the start-up characteristics of various ultrasonic tool heads and prevent tool heads from cracking.
5. Automatic frequency following: Once the generator finds the frequency of the transducer, it can operate continuously without adjusting the frequency of the generator.
6. Amplitude control: When the load changes during the working process of the transducer, it can quickly and automatically adjust the drive to ensure that the transducer can get the most effective frequency power and maintain the amplitude of the tool head.
7. Voltage compensation: When the input external voltage changes, the generator can quickly respond to the adjustment drive to ensure that the transducer can get the most effective frequency electric energy, and maintain the tool head amplitude and power stable output.
8. 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.
