35Khz Ultrasonic Handheld Ultrasound Digital Power Driver for Spot Welder
Description:
The design of the intelligent ultrasonic generator largely determines whether the ultrasonic device can work normally and efficiently. The matching of the ultrasonic episode to the transducer includes two aspects: impedance matching and tuning matching. Impedance matching transforms the impedance of the transducer into an optimal load, ie, an impedance transformation. Tuning matching allows the voltage and current across the transducer to be in phase, resulting in the highest efficiency, while series resonance improves the voltage across the transducer, which is beneficial for piezoelectric transducers.

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.fc
