2025年パキスタン向け製品概要と市場関連性

Silicon Carbide (SiC) bidirectional converter modules enable high-efficiency power flow between batteries, DC buses, and the AC grid—forming the core of modern Battery Energy Storage Systems (BESS) and microgrids. Built on 1200–1700 V SiC MOSFETs and Schottky diodes, these modules deliver ultra-low switching losses, fast transient response, and compact footprints for industrial applications in Pakistan’s textile, cement, and 鉄鋼 sectors as well as emerging data centers and industrial parks.

2025年にこれが重要な理由：

• Pakistan’s grid instability—voltage sags, outages, and frequency excursions—drives demand for hybrid UPS/BESS and microgrids that can ride through events, peak shave, and reduce diesel use.
• Rising tariffs and PKR volatility amplify the value of efficiency: SiC’s >98% conversion minimizes kWh losses, reduces cooling needs, and shortens payback.
• Industrial parks in Karachi, Lahore, and Faisalabad are deploying distributed energy (PV + BESS + gensets) to stabilize operations and meet sustainability goals aligned with NEECA guidelines and evolving utility interconnection standards.
• Medium- to high-power UPS and process drives can be augmented with SiC bidirectional stages for energy arbitrage, harmonic mitigation (THDi <5%), and grid services.

Sicarb Tech supplies modular, application-ready SiC bidirectional DC–DC/AC converters, complete with high-temperature gate drivers, ceramic heat spreaders (R‑SiC, SSiC, RBSiC, SiSiC), digital controls, and comprehensive test and burn-in validation—backed by the Chinese Academy of Sciences and 10+ years of SiC manufacturing experience.
