I'm currently repairing my total brand single board welder. It has blown 2 IGBTs. Till now i haven't found any causes. Any pointers? What normally causes inverter IGBTs to blow? Thank you for such a great tutorial. It has been helpful.

[@tapaskumarbhar6206]

Many many thanks to you .

[@aravindakshanm2705]

Series resistor is ntc not ptc. When switch on time ntc is high value capacitor is slowly charging.when heating ntc resistance comes down.the purpose of ntc is to reduce switch on surge current of capacitors. And protect rectifier also .

[@7gurshaansingh6thmarigold58]

Most welcome

[@saleemkhan-mx9jw]

Sir very useful video.

[@baskantukumar4452]

Good sir.

[@elmnaoirfer3751]

Hello, does the frequency change, through feedback, or is the pulse width the one that changes with a fixed frequency, to fix the output voltage, to the required voltage, thank you very much

[@saralelectronics642]

its the pulse width...(frequency is fixed) no change in frequency. pulse width does the output current rise or fall...as per current control settings

[@saleemkhan-mx9jw]

Thanks again.

[@raidasmurmu8426]
