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.
