2025 Productoverzicht en Marktrelevantie voor Pakistan

Silicon Carbide (SiC) isolated DC/DC converter modules provide the protected auxiliary rails needed to operate high-voltage UPS, VFDs, rectifiers, and renewable interfaces. These modules generate reinforced-isolated supplies for gate drivers (±15/18 V, +6 V, +12/15 V), control electronics (5/12/24 V), sensors, and relays—while tolerating high common-mode transients from fast SiC switching. For Pakistan’s textile, cement, and staal sectors, as well as emerging data centers in Karachi, Lahore, and Faisalabad, SiC-based isolated DC/DC modules elevate reliability under heat, dust, and frequent grid disturbances.

Waarom dit belangrijk is in 2025:

• High CMTI resilience: With SiC inverters switching at 50–100 kHz and dv/dt > 50–100 kV/μs, auxiliary supplies must remain stable and immune to common-mode noise to avoid false trips.
• Efficiency and thermal budget: 92–95% converter efficiency reduces cabinet heat and fan energy, aiding >98% system-level efficiency targets.
• Compact, modular deployment: High-frequency isolation allows smaller magnetics and filters, shrinking control bays by 20–30% and simplifying retrofits.
• Safety and compliance: Reinforced isolation and creepage/clearance dimensioning support IEC/UL standards, essential for critical infrastructure audits and tenders.

Sicarb Tech designs high-CMTI isolated DC/DC modules around SiC-based primary switches, planar magnetics, and reinforced digital isolation, backed by Chinese Academy of Sciences expertise and a decade of SiC manufacturing. Our modules are proven in harsh industrial environments across Pakistan.

Veelgestelde vragen en antwoorden van experts

• Q: What CMTI should I target for totem‑pole PFC and three-level UPS?

• Q: Can one module power multiple gate drivers?
  A: Yes, but we recommend isolated rails per leg/phase to prevent cross-talk. Multi-output versions provide independent regulation and current limits.

  A: <30–50 mVpp with our default filters; lower ripple achievable with optional LDO post-regulators for sensitive sensors.
• Q: Deployment time?
  A: 7–12 business days per site including mechanical fit, wiring, EMI validation, and functional tests; faster for DIN-rail variants.
