20KHZ 1200W Low Frequency Ultrasonic Generator Adjustable Power For Cleaning Industrial Parts

In the design of the ultrasonic power source, the matching design of the generator and the transducer is very important, and to a large extent determines whether the ultrasonic equipment can work normally and efficiently. The matching of ultrasonic generator and transducer includes two aspects: impedance matching and tuning matching. Impedance matching transforms the impedance of the transducer into the optimal load, that is, plays the role of impedance transformation. Tuning matching makes the voltage and current at both ends of the transducer in phase, so as to maximize the efficiency. At the same time, series resonance can increase the voltage at both ends of the transducer, which is beneficial to the excitation of the piezoelectric transducer.
In recent years, the application of ultrasonic in industry has continuously emerged, such as ultrasonic flaw detection, ultrasonic cleaning and so on. With the popularity of ultrasound research, how to effectively produce the ultrasonic power source that meets the requirements has also become urgent, and its performance characteristics directly affect the ultrasound research work. The above research requires ultrasound to have the characteristics of high resolution, high stability, high power, and wide range of adjustable frequencies. For this reason, this paper proposes a field programmable logic gate array (FPGA)-based DDS technology to generate ultrasound power The source of the program, and has been applied to the actual acoustic research.
Power ultrasonic equipment uses the energy of ultrasonic waves to change certain states of materials and needs to generate considerable or relatively large power. The ultrasonic power source (or generator) provides continuous electric energy to the ultrasonic transducer, and its performance characteristics directly affect the research work of various power ultrasonics. In recent years, the research on power ultrasound in our country is very popular, especially the biological effects of ultrasound chemistry and ultrasound, which are also the focus of acoustic research. The above-mentioned research requires ultrasound to have the characteristics of high resolution, high stability, high power, and wide range of adjustable frequencies. For this reason, an ultrasound power source based on DDS technology has been developed and has been applied in actual acoustic research. .
