Design of LC Resonant Inverter for Ultrasonic Metal Welding system

The ultrasonic welding is with features of high electric conductivity and hot conductivity when it is used in various metallic bonds, excellent quality when it is used for advanced junction, easiness when it is used in various metallic bonds, needless for the exhaustive material and benefit for the environment. Currently the use of ultrasonic welding is increasing in the industrial fields such as the automobile battle, the refrigerator, the air conditioner, the battery and the solar cell junction. In this paper, the output LC resonance filter and 35kHz square-wave-generating Full Bridge circuit was designed and tested. The output examination of the ultrasonic oscillator and the ultrasonic welding examination were done. The method for getting more efficient result in the ultrasonic welding system was researched.
