LCD Screen Ultrasonic 20Khz Digital Generator Automatic Trancking Frequency

Description:

Ultrasonic generators, commonly referred to as ultrasonic power boxes, ultrasonic sources, and ultrasonic power supplies. Its function is to convert our mains (220V or 380V, 50 or 60Hz) into a high frequency AC signal that matches the ultrasonic transducer. From the form of the amplifying circuit, a linear amplifying circuit and a switching power supply circuit can be used, and a high-power ultrasonic power source generally adopts a circuit form of a switching power supply in terms of conversion efficiency. Linear power supplies also have their own range of applications. It has the advantage of not requiring strict circuit matching and allowing continuous and rapid changes in operating frequency. From the current situation in the ultrasound industry, ultrasonic generators are mainly divided into self-excited and its exciting power supplies.

Distance between Analog generator and Digital generator:

The analog control circuit has the disadvantages of low control precision, slow dynamic response, inconvenient parameter setting, severe temperature drift, and easy aging. The advent of dedicated analog integrated control chips greatly simplifies the control circuitry for power electronic circuits. The switching frequency of the signal is improved, and only a plurality of external RC components can directly constitute an analog regulator with a correction link, thereby improving the reliability of the circuit. However, due to the existence of the RC components, the inherent defects of the analog control circuit, such as the accuracy and consistency of the component parameters, and the aging of the components still exist. In addition, the analog integrated control chip also has problems of large power consumption, low integration, inflexible control, and low versatility.

The use of digital control instead of analog control can eliminate the shortcomings that conventional analog regulators such as temperature drift are difficult to overcome, facilitate parameter tuning and variable parameter adjustment, facilitate the change of program software, adjust control schemes and implement various new control strategies. At the same time, the number of components can be reduced, the hardware structure can be simplified, and the system reliability can be improved. In addition, automatic storage of operation data and automatic fault diagnosis can be realized, which helps to realize the intelligent operation of the power electronic device.
