piezoelectric transducer resonant frequency 28khz/40khz ultrasonic
transducer
Tuning matching plays an important role in the system of ultrasonic
generator. First, when the ultrasonic transducer is in the resonant
state, it usually presents a capacitive state. Through matching
network, the capacitive impedance is compensated, so that the load
of the ultrasonic generator is as close as possible to the pure
impedance state, so as to reduce the reactive power component.
Impedance matching: According to AC theory, when the power supply
impedance and load impedance are equal, the load can obtain the
maximum power. Because the ultrasonic transducer has the
characteristic of impedance model, the impedance characteristic of
the power supply load of the whole ultrasonic generator is changed
by matching network, and the appropriate parameters are selected to
make the load impedance close to the power supply impedance, so
that the ultrasonic wave can obtain larger electric power. At
present, domestic and foreign scholars have carried out in-depth
research on the matching network of ultrasonic transducers. Based
on the equivalent circuit, a simple L-C matching network is used to
obtain the maximum conversion power and improve the efficiency of
the ultrasonic transducer.
From the perspective of excitation mode of ultrasonic transducer,
it can be divided into two excitation modes: self-excitation mode
and self-excitation mode. Because the vibration modes of the two
generators are different, for its excitation generator, it is
necessary to know the specific parameters of the ultrasonic
transducer, including the working frequency. The inductance value
to be connected can be roughly calculated by calculating formula,
while the self-excitation generator usually determines the working
frequency by connecting the inductance value. From the point of
view of impedance matching, how to do this is analyzed. A matching
network is composed of a pulse transformer and R, L and C between
the generator and the ultrasonic transducer. Based on the analysis
of the basic principle of ultrasonic transducer and the electrical
equivalent circuit, the capacitance matching, inductance matching,
LC matching and T-type matching are studied, and the basic
calculation methods of these matching modes and parameters are
given, and each matching is analyzed. The advantages and
disadvantages of these two matching methods have good reference
value for static matching. By analyzing the characteristics of
series inductance matching and parallel inductance matching on the
frequency of ultrasonic transducer, combining the advantages of
these two matching methods, an L-type matching network is proposed,
and the effects of these matching methods on working frequency and
the changes of electromechanical coupling coefficient are compared,
which provides one for static matching network. Ways of planting.
