You will be diagnosing failed drives down to the component, repairing them, and load-testing them before dispatch. This is a workshop bench role, with occasional site visits to customer plants.

What you will do: Receive failed VFDs, take fault history from the customer, and carry out systematic diagnosis — input rectifier, DC bus, IGBT module, gate driver circuit, SMPS/control supply, current sensors, control card Trace faults at component level using multimeter, oscilloscope, LCR meter and ESR meter Replace IGBT modules, thyristor/diode bridges, DC link capacitors, driver ICs, current transducers, cooling fans and relays; carry out clean soldering and desoldering on multi-layer boards Run the repaired drive on load bank / test motor, verify output waveform balance, thermal behaviour and trip response before clearing it for dispatch Maintain a repair record for every unit: fault found, root cause, parts replaced, test results Identify failure patterns and advise customers on root causes — supply quality,



overload, ambient temperature, cable length, cooling Attend customer sites for drive commissioning, parameter setting and breakdown support when required Keep the workshop, ESD practice and spares inventory in order Must have Hands-on component-level repair of VFDs, or of closely related power electronics online UPS, servo stabilizer, welding inverter, solar inverter, DC drives, SMPS Ability to read and follow power and control circuit diagrams Confident use of multimeter and CRO; comfortable checking IGBT and rectifier health with diode test Practical soldering / desoldering skill on SMD and through-hole boards Understanding of three-phase power, PWM inverter basics and drive protection trips (OC, OV, UV, OL, earth fault, phase loss) Electrical safety discipline — DC bus discharge, ESD handling, LOTO
