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
