파키스탄용 2025년 제품 개요 및 시장 관련성

High-frequency silicon carbide (SiC) power factor correction (PFC) control units are the brains of ultra‑efficient AC front ends for UPS, VFDs, rectifiers, and high‑power industrial power supplies. By coordinating SiC MOSFETs and SiC Schottky diodes in bridgeless totem‑pole or interleaved boost topologies at 50–100 kHz, these controllers deliver PF >0.99 and THDi <5% at the Point of Common Coupling (PCC)—even under voltage sags, load steps, and harmonic‑rich grids.

This is a strategic upgrade for Pakistan’s textile, cement, and 강철 plants—and for data centers and industrial parks in Karachi, Lahore, and Faisalabad—where grid instability, heat, and dust elevate downtime risk and energy costs:

• Efficiency and compliance: Raising input PF and suppressing current harmonics cuts transformer heating and utility penalties, while boosting end‑to‑end converter efficiency toward and beyond 98%.
• Compact retrofits: High switching frequency enables smaller magnetics and filters, reducing cabinet volume by 30–40%—ideal for brownfield electrical rooms.
• Resilience: Fast digital control loops stabilize DC links during sags and flicker, protecting continuous processes and IT loads.
• Fast deployment: Modular control units integrate sensing, gate-drive coordination, and communications, accelerating commissioning with local SCADA and BMS.

Sicarb Tech’s PFC control units integrate high‑CMTI isolated gate drivers, precision current/voltage sensing, adaptive digital control, predictive diagnostics, and OT‑grade communications. Backed by the Chinese Academy of Sciences and 10+ years of SiC manufacturing and control expertise, we deliver turnkey front‑end performance for Pakistan’s mission‑critical facilities.
