Ultrasonic generator
, usually called ultrasonic electrical boxes, ultrasonic source, ultrasonic power supply. Its function is to put our utility (220V or 380V, 50 or 60Hz) convert and ultrasonic transducer matching high-frequency ac signals. From the amplifier circuit form, can use linear amplifier circuit and switching power supply circuit, high-power ultrasonic power from the conversion efficiency into consideration generally USES of switch power supply circuit form. Linear power also has its own application scope, its advantage is that it can not strictly required circuit matching, allowing the working frequency continuous rapid change. From the current ultrasonic industry showed that ultrasonic mainly divided into ZiJiShi and it separate-excited power supply.

Generator is principle was first made by signal generator to produce a particular frequency of the signal, the ultrasonic generator
A signal may be sine signals, also can be the pulse signal, this particular frequency is transducer frequency, normally used in ultrasonic equipment for the ultrasonic frequency 20KHz, 25KHz, 28KHz, 60KHz; 33KHz, 40KHz, 100 KHZ or above now has not been used in large amounts. But along with the continuous development of later precision cleaning. Believe that use face will gradually enlarged.

Ultrasonic generator provides power output signal:

Comparatively perfect ultrasonic generator also should have the feedback part, mainly provides two aspects of feedback signal: the first is to provide power output signal, we know that when the power supply voltage generator () changes. Generator output power also can produce change, at this moment is reflected in the mechanical vibration transducer is small, leading to large suddenly suddenly cleaning effect is not stable. Therefore requires a stable output power through power feedback signals corresponding adjustment power amplifier, making the power amplifier stability.

Ultrasonic generator provides frequency tracking signal:

The second is to provide frequency tracking signal. When transducer working in resonance frequency point at its highest efficiency, work is the most stable, and the resonant frequency transducers due assembly work ageing hind reason and change, of course, the change of frequency just drift, change is not very big, frequency tracking signal can control signal generator, make signal generator frequency within a certain range tracking transducer resonant frequency points. Let generator work in the best state. Of course as modern electronic ultrasonic technology, especially the microprocessor (uP) and signal processor (DSP) development, generator function more and more powerful, but no matter how changes, its core functions should be mentioned, but the content of each part in the realization of the ultrasonic technology different ways.

Ultrasonic generator frequency trimming function

Ultrasonic generator have frequency fine-tune the function, adjusting scope of 2%, in different conditions slightly adjustment makes transducer work consistently in the best condition, change can achieve maximum efficiency, in different conditions were able to achieve the best effect.
Sweep frequency function
Ultrasonic generator with sweep frequency function, through the cleaning process ultrasonic frequency in rational scope reciprocating SaoDong, driving the cleaning fluid backflow, make the workpiece formed subtle dirt by ultrasonic disbonding simultaneously in rapidly take away from the surface of workpiece, improve cleaning efficiency.
Power regulating function
Ultrasonic generator with power control functions, output power can realize 10% - 100% of the continuous adjustment in order to adapt to the requirements of various cleaning object.
