2011 International Conference on Computer Science and Information Technology (ICCSIT 2011) IPCSIT vol. 51 (2012) © (2 012) IACSIT Press, Singapore DOI: 10.7763/IPCSIT.2012.V51.74 The Research of Ultrasonic Equipment Applied In Non-woven Welding + Chen Wei and Li Suxun The School of Information Science and Technology,Xiamen University, Xiamen and 361005, China Abstract. In the paper, an ultrasonic atomization welding system is discussed, which composed of the high frequency ultrasonic power supply and the transducer. The high frequency ultrasonic power supply provides appropriate electric for the transducer, and the transducer transforms the electric energy into the ultrasonic kinetic energy. This paper is focus on the theory analysis and the design of the power supply. Based on the analysis and argument of ultrasonic welding power, for ultrasonic welding of the specific requirements, designed the rectifier filter circuit, power amplifier, frequency track circuit, matching circuit, drive and protection circuit. In addition, analyzed the main part of the rectifier filter circuit, power conversion and other parts, gave the parameters of calculation and choice of methods.
