DC SYSTEMS Product Lines We Repair
Our engineers are trained on the full DC SYSTEMS product range. Below are the major product families we service.
Industrial DC Rectifier Modules
Three-phase to DC conversion systems with SCR or diode bridges for plating, electrorefining, and electrochemical processes. Common failures include thyristor failures, transformer secondary winding shorts, and control circuit faults affecting output voltage regulation.
DC Drive Controllers
Regenerative and non-regenerative DC motor drives with integrated field control and armature power stages. Repairs often involve IGBT module failures, gate driver circuit faults, current sensing errors, and firmware corruption preventing motor acceleration.
Power Supply and UPS Modules
Regulated DC power supplies and uninterruptible power systems for PLC, HMI, and servo control circuits. Typical faults include capacitor bank failures, transformer lamination breakdown, PWM controller IC failures, and battery charger circuit malfunctions.
EV Charging Power Stages
DC fast-charging rectifier and power conversion modules for electric vehicle infrastructure across Indian EV charging networks. Failure modes include PFC stage losses, DC bus capacitor degradation, isolated gate driver failures, and CAN communication faults.
Renewable Energy Integration Units
Solar DC-to-AC inverter stages and battery storage DC conditioning modules used in Indian solar farms and microgrids. Common issues are MPPT algorithm freezes, battery pre-charge resistor overheating, isolation transformer faults, and DC link voltage instability.
Industrial Plating and Electrochemistry Systems
Constant-current and constant-voltage DC supplies for electroplating, metal finishing, and anodizing operations. Repairs address SCR commutation failures, ripple filter capacitor aging, current feedback sensor drifts, and voltage programming circuit faults.

Common DC SYSTEMS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DC SYSTEMS equipment arriving at our workshop.
- ✓SCR/Thyristor module failure — no DC output — DC SYSTEMS rectifier units use silicon-controlled rectifiers for phase control. SCR failure occurs due to gate-cathode insulation breakdown from thermal cycling, moisture ingress, or gate driver overvoltage spikes from inductive loads.
- ✓Armature voltage ripple and motor torque pulsation — DC SYSTEMS DC drive controllers use bridge rectifier stages or PWM modulators. Ripple increases when smoothing capacitors degrade, filter inductors saturate, or the PWM switching frequency drifts due to oscillator IC aging or control software corruption.
- ✓Power supply output drifting or collapsing under load — Feedback network faults in DC SYSTEMS power supply modules cause voltage regulation loop instability. Common root causes are optocoupler degradation (CTR drop), voltage reference IC drift, output inductor parasitic resistance increase, and PWM IC saturation from noise injection.
- ✓EV charger unable to reach full DC output current — DC SYSTEMS EV charging power stages fail due to PFC inductor saturation, gate driver rail collapse from MOSFET crossover losses, DC bus capacitor voltage sag, or current-sense amplifier offset drift exceeding DC SYSTEMS tolerance bands.
- ✓CAN communication loss or fault codes E01, E05, E12 — DC SYSTEMS industrial drives and EV chargers use CAN-bus for remote commands and telemetry. Faults originate from isolation optocoupler failures, CAN transceiver IC damage from field induced surges, PCB trace corrosion in damp mill environments, or software watchdog timeout.
- ✓Battery charger module overheating or not charging — DC SYSTEMS UPS and EV charging battery charger circuits use resistive current-limiting or LDO regulation stages. Failures stem from thermal runaway due to faulty temperature sensor, shorted charge-path FETs, transformer primary winding faults, or insufficient heatsink contact pressure.

Frequently Asked Questions — DC SYSTEMS Repairs
Do you repair DC SYSTEMS equipment anywhere in India?+
Yes. Synchronics repairs the full DC SYSTEMS product range across India — rectifier modules, DC drives, power supplies, and EV charging systems. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. All equipment is serviced and tested at our main facility in Vadodara, Gujarat.
What is the typical turnaround time for a DC SYSTEMS rectifier repair?+
For standard DC SYSTEMS rectifier module repairs, our average turnaround is 3-5 working days depending on component availability. If the fault is a thyristor failure or capacitor replacement, turnaround is often 24-48 hours since we maintain stock of common DC SYSTEMS components. Complex firmware rewrites or transformer failures may extend to 7-10 days. Synchronics offers express service for critical production lines.
Can Synchronics repair DC SYSTEMS EV charger power stages with CAN communication faults?+
Absolutely. DC SYSTEMS EV charging modules frequently fail due to CAN transceiver damage, isolation optocoupler aging, or firmware watchdog resets. Synchronics has full test equipment to verify CAN signal integrity, replace isolated gate drivers, and reload the latest DC SYSTEMS firmware calibrations. We've successfully restored communication and charging speed on EV chargers across 50+ installations in India.
Do you provide warranty on DC SYSTEMS rectifier repairs?+
Yes. All DC SYSTEMS repairs completed by Synchronics come with a 12-month warranty on parts and labor. If a repaired rectifier fails within warranty due to workmanship, we repair it at no charge. We also provide 24-month warranty on replacement power semiconductors if purchased through us for customer self-service repairs.
How do I know if my DC SYSTEMS power supply needs repair versus replacement?+
Send your power supply unit to Synchronics for free diagnostic testing. We measure output voltage stability under load, check capacitor ESR values, verify PWM frequency, and test the feedback regulation loop. If repair cost is less than 40% of a new unit and we can source components, repair is recommended. For aging units (10+ years), replacement often makes economic sense despite high repair cost.
How do I send my DC SYSTEMS unit for repair?+
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.
What is the cost of repairing a DC SYSTEMS drive or PLC?+
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.
What warranty do you provide on DC SYSTEMS repairs?+
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.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DC SYSTEMS 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.
