Design of Inverter AC PMIG Welding Power Source based on MCU
Yixiong Wu · IEEE Transactions on Power Electronics · 2006
The constitution and operating principle of AC PMIG inverter welding power source based on 80C196KC single chip microcomputer are introduced.The hardware design and software program of the welding power source are discussed in detail.The primary inverter driving circuit,current foldback circuit,protection circuits for overheat and low-voltage circuit are introduced specially.Tests shown that AC PMIG welding power source runs reliably and stably,it can satisfy the welding process requirement.
