#91 Inverter IGBT Welder Machine (Part -2) Output Rectifier Circuit Explained & Troubleshooting

To watch Part 1 of this video • #90 Inverter IGBT Weld...
Part 3 of this video • #92 Inverter IGBT Weld...
in this video i discussed the circuit diagram and how to repair and troubleshoot inverter IGBT based welding machine. in this section i discussed the high frequency ferrite core high current transformer and the output rectifier circuit. the smps transformer takes input drive from IGBT transistors and the center tapped secondary is connected the molded D92-20 rectifier set connected in parallel. there is a shunt which is used as a current sense. the SG3525 IC provides a drive signal to the IGBT gates through gate driver network.
this china MMA-200T Inverter IGBT Welder Machine - Circuit Explained & Troubleshooting Part -1, is single phase 220 VAC operated. it have a bridge rectifier which rectifies the main ac voltage into dc voltage, which are connected to pair of dc capacitors through a relay contacts and in parallel 110 ohms ntc resistor. this nts protects from inrush current and upon receiving relay drive signal it switches the rectified voltage to capacitors so, the ntc is bypassed to get full current to drive igbt.
after watching this video you will learn:-
how to #repair #inverter #igbt #welding machine or welder
2. functional description of inverter igbt welder machine
3. how to troubleshoot arc welding machine
4. how to understand mma-200 circuit diagram and how it works
5. if welding machine does not work, how you will repair
6. if main circuit breaker trips off when power switch is turned on
7. over current OC LED light turns on
