EUPEC Repair Services India

Yes. Synchronics repairs the complete EUPEC power semiconductor module range — IGBT modules, thyristor stacks, diode rectifiers, and gate drive circuits. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, and all other major cities. Modules are transported in climate-controlled packaging to our fully equipped facility in Vadodara, Gujarat, where they undergo detailed electrical characterization, thermal profiling, and remanufacture per EUPEC engineering standards.

Threshold voltage (Vgs(th)) is the gate-source voltage at which an IGBT begins to conduct, typically 2.5-5 V for EUPEC modules. Drift in Vgs(th) due to gate oxide degradation slows switching, increases losses, and can cause cross-conduction in parallel modules. Synchronics measures Vgs(th) at multiple gate currents using precision curve tracers, validates against EUPEC datasheets, and documents test reports for regulatory compliance in power systems.

Yes. Synchronics specializes in remanufacturing EUPEC FF (fast field-stop) and FZ (field-stop) series IGBTs. We disassemble modules, inspect silicon die and ceramic substrates under microscopy, replace failed dies with matched EUPEC stock, re-solder all joints using thermal profiling, restore thermal interfaces with OEM-approved compounds, and conduct full electrical and thermal validation. Remanufactured modules are 30-40% more cost-effective than new stock while meeting original performance specifications.

EUPEC gate driver circuits use optocouplers to isolate high-voltage signals from control electronics. Synchronics tests optocoupler current transfer ratio (CTR), propagation delay, and rise/fall times using dedicated optocoupler testers. Failed units show low CTR (<60%), excessive propagation delay (>1 µs), or inability to meet switching timing margins. We replace faulty optocouplers with drop-in equivalents, validate gate signal timing at the IGBT terminals using 4-channel oscilloscopes, and re-certify the driver board before return to service.

Synchronics prioritizes EUPEC module repairs based on complexity and customer criticality. Standard faults (thermal interface refresh, solder rework, gate drive repair) are completed in 5-7 working days. Complex remanufacture (die replacement, full parametric re-test, thermal cycling validation) requires 10-15 days. Urgent industrial breakdowns receive expedited service with same-city pickup and next-day diagnostics. All work includes comprehensive test reports, warranty certification, and reverse logistics prepaid.

Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.

Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.

All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.

Yes. If we cannot repair your EUPEC unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
