Power Quality and Efficiency for Pakistan’s Industrial Growth in 2025

Pakistan’s textile, cement, and 鉄鋼 industries—along with rapidly expanding wind and solar assets—require robust, compact, and efficient power conversion. High-frequency silicon carbide (SiC) power modules deliver >98% conversion efficiency and sub-10 ms dynamic response for Static Var Generators (SVG/STATCOM), Active Power Filters (APF), and medium-voltage (MV) drives. These capabilities help facilities meet NTDC/NEPRA interconnection criteria, align with IEEE 519 and IEC 61000-3-6 harmonic guidelines, and sustain performance in high ambient temperatures common in Sindh and South Punjab.

Sicarb Tech, located in Weifang City (China’s SiC hub) and backed by the Chinese Academy of Sciences, provides custom-engineered SiC modules and turnkey technology transfer. With 10+ years of SiC manufacturing and 19+ successful deployments, our modules reduce losses, footprint, and maintenance while accelerating compliance and ROI for Pakistani plants and renewable plants.
