A very strong smps power supply is being used for warming cooking, welding 🙂 The system is generally built on the stern uc3845 integral but gives a gigantic power when the igbt STGW30NC60WD power transistors enter into the workout output voltage can be set from 3v sistem 60v to a mik smps made with uc3845 supply tny267 current transformer is used for over-current protection.
