HV TECHNOLOGY Product Lines We Repair
Our engineers are trained on the full HV TECHNOLOGY product range. Below are the major product families we service.
MVDRIVE Medium-Voltage Variable Frequency Drives
Modular MV drives for cement kilns, compressors, and pump motors rated 500 kW to 10 MW. Common issues include IGBT module thermal stress, DC bus capacitor ageing, and gate drive board failures under harmonic-rich Indian grid conditions.
SoftStart High-Voltage Soft Starters
Thyristor-based soft starters for 3.3 kV to 11 kV motors in mining and steel rolling mills. Typical faults: thyristor triggering circuit instability, snubber capacitor breakdown, and control board contamination from industrial dust and humidity.
PowerControl Rectifier and DC Supply Units
Industrial-grade rectifier modules and DC power supplies for electroplating, DC motor drives, and battery charging systems. Common failures: transformer core saturation, diode module burnout, and voltage regulation circuit drift.
HV Filter and Harmonic Compensation Systems
Active and passive harmonic filters for 3.3 kV and 6.6 kV networks in steel plants and cement mills. Repair involves capacitor bank testing, reactor coil insulation assessment, and active filter control card reprogramming.
Control and Protection Electronics
HV control boards, protection relays, and voltage/current transducers for switchgear integration. Failure modes include solder joint fatigue from thermal cycling, optocoupler degradation, and firmware corruption.

Common HV TECHNOLOGY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HV TECHNOLOGY equipment arriving at our workshop.
- ✓MVDRIVE IGBT module thermal runaway and gate drive failure — In Indian industrial environments with high ambient temperatures (40-50°C), inadequate cooling airflow in cement plant or steel mill switchgear enclosures leads to IGBT junction temperature exceeding 120°C. Gate drive board IC (typically IR2110 or equivalent) fails due to thermal stress, causing erratic gate pulse delivery and phase imbalance.
- ✓SoftStart thyristor snubber capacitor ESR failure and voltage spikes — Mining and steel rolling applications with rapid load transients and harmonic distortion (THD 8-15% common in Indian mills) cause snubber capacitor electrolyte degradation. Aluminum electrolytic capacitors rated for 480V fail under transient overvoltages exceeding 1.5 kV, creating uncontrolled dV/dt.
- ✓PowerControl rectifier transformer core saturation and overheating — Electroplating and DC drive applications in Indian foundries operate with unfiltered DC bus and poor mains waveform. Transformer core experiences AC magnetisation losses, core eddy currents increase, temperature rises, and insulation lifetime decreases exponentially.
- ✓HV Filter capacitor bank failure — swelling, venting, and bank derating — Cement plants and steel mills with continuous 24/7 operation at 90-100% load in tropical Indian climates experience capacitor bank thermal stress. Switching transients and resonance with plant reactors create voltage stress on capacitor terminals; units swell, vent, and degrade in groups.
- ✓Control board solder joint fatigue and cold solder cracking — HV TECHNOLOGY control and protection boards in Indian switchgear enclosures experience extreme thermal cycling (±20°C daily swing) due to seasonal ambient changes and high-current operation. Pb-free solder joints on heavy components (transformers, relays, connector pins) develop micro-fractures and intermittent opens.
- ✓Firmware corruption and bootloader lockout on HV control modules — Power supply transients, ESD events during maintenance, or interrupted firmware uploads during on-site upgrades cause HV TECHNOLOGY control module microcontroller memory corruption. Device enters bootloader loop or executes corrupted code, resulting in loss of drive control and protection function.

Frequently Asked Questions — HV TECHNOLOGY Repairs
Do you repair HV TECHNOLOGY equipment anywhere in India?+
Yes, absolutely. Synchronics Electronics is the leading authorised repair centre for HV TECHNOLOGY MVDRIVE, SoftStart, PowerControl, and Filter systems across India. We offer PAN India door-to-door equipment pickup and transport from all major industrial cities — Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and Bengaluru. All repairs are performed at our state-of-the-art 180-engineer facility in Vadodara, Gujarat. Typical turnaround: 7-10 working days including testing and spare parts stocking.
What is the cost and timeline for HV TECHNOLOGY MVDRIVE repair in India?+
HV TECHNOLOGY MVDRIVE repair costs depend on fault severity — IGBT module replacement runs INR 65,000-1,50,000 (labour + parts), while gate drive board repair costs INR 18,000-35,000. Full system recalibration and burn-in testing adds 3-5 days. Synchronics offers fixed quotes after free telephone fault diagnosis. We source genuine HV TECHNOLOGY IGBT modules, capacitors, and PCB assemblies in India and maintain stock to minimise delays. Expedited repair (5-7 days) available at 15% premium.
Can you repair HV TECHNOLOGY soft starters with thyristor failures in cement and steel mills?+
Yes, we specialise in HV TECHNOLOGY SoftStart thyristor repair and replacement. Thyristor modules (typically Semikron, IXYS, or Infineon components) are tested using curve tracing equipment, then replaced if leakage current exceeds specification. We also upgrade snubber networks to polypropylene capacitors and suppress transient overvoltages with high-speed diodes, improving reliability in Indian mills with poor power quality (THD >10%). Average repair: 6-8 days including load testing simulation.
Does Synchronics stock spare parts for HV TECHNOLOGY equipment?+
Yes. Synchronics maintains a rotating stock of critical HV TECHNOLOGY spare parts — IGBT modules, gate drive cards, snubber capacitors, thyristor modules, rectifier diodes, control transformers, and firmware for all MVDRIVE, SoftStart, and PowerControl series. Emergency parts requests are fulfilled within 24-48 hours. We also source custom components directly from HV TECHNOLOGY suppliers in Germany and stock Indian-sourced components from authorised distributors in Delhi and Mumbai. Lead time for unavailable parts: 10-14 days.
What happens if HV TECHNOLOGY fault codes appear but equipment is not repairable by plant technicians?+
Synchronics provides remote phone fault diagnosis for HV TECHNOLOGY equipment. Send us a photo of the fault code display (e.g., overtemp, overvoltage, phase loss, IGBT fault) and equipment dataplate, and we will advise repair urgency and provide troubleshooting steps. If on-site repair is not possible, we arrange immediate pickup. Most HV TECHNOLOGY faults — gate drive errors, thyristor faults, capacitor ESR rise — are repairable. Failure rate: <2% of received equipment requires replacement rather than repair.
How do I send my HV TECHNOLOGY 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 HV TECHNOLOGY 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 HV TECHNOLOGY 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 HV TECHNOLOGY 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.
