| Summary: | 碩士 === 淡江大學 === 電機工程學系碩士班 === 104 === Welding technology boost the develop speed of industry. Customers involve various metal processing industry, shipyards, oil fields, factories, building construction, aerospace technology, traditional electroplating and metal welding related industries. Currently on the welding machine functions, in addition to the requirement of welding precision, high output power and high reliability increasing, the output function for the special needs of different applications also rose sharply. How to deal with multiple customized, lightweight, highly adjustable accuracy and other customer needs, is now the focus of product development.
With respect to the analog, the biggest advantage of digital systems is high precision. In analog system, through operational amplifier circuit because of the slight error cause by environment, using the digital system will be able to solve this issue.
In this thesis, the FPGA develop board can control the main functions of welding machine: inverter, gas and wire feeding safely.
