Abstract

 

This paper describes a robust circuit design using matching technology to drive the ultrasonic welding transducer with zero voltage switching. A new feedback control method to track the optimal working frequency was practically implemented by a FPGA chip. All analytic results exhibited that the newly designed class-E inverter circuit can be effectively and stably applied on the high power ultrasound welding system.

 

Key words: Class-E inverter, matching technology, ultrasound welding, zero voltage switching.
