Ultrasonic generator, also known as ultrasonic power supply, ultrasonic electronics box, ultrasonic controllers, which is an important component of high-power ultrasound system.
The role of Ultrasonic generator is to convert electric supply to high-frequency AC signal matching the ultrasonic transducer, then drive ultrasonic transducer to work. Considering the conversion efficiency, high-power ultrasonic gerally adopts switching mode power supply circuit type. Ultrasonic power supply is divided into self-excitation, and external force excitation power, while self excitation power called ultrasonic analog power, external force excitation power called as ultrasonic generator.
Ultrasonic generator description:
Ultrasonic generator using the world’s leading external force excitation power oscillation circuit structure, representing the self excitation oscillation circuit structure, its the output power increased by 10%. Ultrasonic amplifying circuit forms as linear amplifier and switching power supply circuit. Advantages of switching model power supply circuit: high conversion efficiency, so high power ultrasonic power supply using this form. Advantages of linear power supply circuit: no strict requirements for circuit matching, allows the operating frequency continuous rapid change.
Ultrasonic generator principle:
An ultrasonic generator to generate a specific frequency, this signal may be a sinusoidal signal, or can be a pulse signal, this particular frequency is the frequency of the transducer to work. Ultrasonic frequency devices are generally used 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz, 80KHz, but has not been widely used for 100KHz or uppon.
Ultrasonic generator feedback signals:
Impeccable ultrasonic generator have feedback node, which offers the following two aspects of the feedback signal.
Output power:
When connection voltage of ultrasonic generator changes, the output powr of generator also changes. Make the ultrasonic transducer mechanical vibration unstable, resulting in poor work results. Hence needs stable output power, through power feedback signal to adjust amplifier, so that make the power amplifier stable.
Frequency tracking:
Transducers operating at the highest efficiency when in the resonant frequency, the most stable work. While transducer resonant frequency will change due to assemblying or working aging. If frequency just drift, changed little, the frequency tracking signal can control signal generator, making the frequency of the signal generator within a certain range of the transducer resonant frequency, so that the generator work in the best condition.
Ultrasonic generator advantages:
Ultrasonic generator can monitor the system operating frequency, power. According to different requirements of users, real-time adjustment of various parameters: such as power, amplitude, and running time. Frequency tuning: adjust the frequency of the ultrasonic transducer is always working in the best conditions, for maximum efficiency, adjusting the range of 2%. Automatic with frequency: Once your device is completed initial setup, generator can continuous operation without the need for adjustment. Amplitude control: the transducer load changes during operation, can automatically adjust the driving characteristics, to ensure that the tool head to get stable amplitude. System protection: when the system work under unfavorable operating environment, the generator will stop working and alarm display, to protect equipment from damage. Amplitude adjustment: amplitude can instantly increase or decrease in the work process, the amplitude setting range: 0% to 100%. Automatic search frequency: automatic determination the tool head working frequency and stored.
