A novel FPGA implementation of a welding control using a new bus architecture

Development of PLDs (programmable logic device) like large FPGA (field programmable gate array) circuits allow those to be used as modern control platforms for power electronics. Using FPGAs and efficient control algorithms better response times can be gained compared to processor implementations. When using a large FPGA circuit an efficient structure has to be used to get a short time to market time and to handle the whole software structure. In this paper a switch-mode welding machine control implementation in FPGA circuit is presented using a new bus structure called OKITO as a base. Also results of fast response times in current control are shown
