2025年パキスタン向け製品概要と市場関連性

Integrated silicon carbide (SiC) UPS rectifier–inverter modules combine high-frequency PFC rectification and three-level inverter power stages into a compact, factory-validated block that delivers exceptional efficiency, fast dynamic response, and high reliability. For Pakistan’s textile, cement, and 鉄鋼 sectors, and for growing data center clusters in Karachi, Lahore, and Islamabad, these modules address grid instability (voltage sags, harmonics, frequent switching) while minimizing energy and cooling costs in PKR.

2025年に重要な理由：

• Efficiency >98%: SiC MOSFETs and SiC Schottky diodes enable high-frequency operation (50–100 kHz) with ultra-low conduction and switching losses, cutting HVAC loads and OPEX.
• Space and deployment speed: Integrated modules shrink cabinet footprint by 30–40% and reduce system integration time—vital for brownfield retrofits in cramped electrical rooms.
• Reliability under heat and dust: SiC’s wide junction temperature capability (up to 175°C) and robust packaging improve uptime in plant rooms reaching 45–50°C with particulate exposure.
• Power quality compliance: Achieves PF >0.99 and THDi <5% at PCC with active PFC and optimized filters, supporting utility approvals and avoiding penalties.

Sicarb Tech’s integrated UPS modules pair high-CMTI gate drivers, reinforced-isolation power stages, ceramic heat spreaders (R‑SiC, SSiC, RBSiC, SiSiC), and intelligent control/diagnostics. Backed by the Chinese Academy of Sciences and a decade of SiC manufacturing, our modules are production-proven for Pakistan’s critical infrastructure and industrial parks.

主な利点と実証済みのメリット

• Reduced OPEX and cooling: High efficiency cuts heat, enabling smaller HVAC systems and lower fan power, directly saving PKR in high-tariff periods.
• Compact, modular scalability: High-frequency operation shrinks magnetics and capacitors; pre-engineered modules simplify parallel N+1 architectures.
• Reliability through protection: DESAT with soft turn-off, high CMTI isolators, and robust surge handling prevent catastrophic failures in unstable grids.
• Compliance and analytics: Native IEC 61850 integration and predictive maintenance speed approvals and reduce unplanned downtime.
