Visión general del producto y relevancia para el mercado en 2025

High-frequency, high-density silicon carbide (SiC) DC power systems integrate SiC MOSFETs and diodes with advanced magnetics, digital control, and robust thermal packaging to deliver compact, efficient DC conversion for telecom sites, edge computing nodes, and industrial DC grids. Operating reliably at elevated ambient temperatures and under grid disturbances common in Pakistan, these systems provide tightly regulated 48–54 Vdc (telecom), 380–400 Vdc (HVDC distribution), and custom DC buses for drives and process equipment.

Why 2025 is pivotal in Pakistan:

• Network densification: 4G/5G expansion and edge computing require compact rectifiers and DC power shelves with high reliability and low OPEX.
• Industrial modernization: Textile, cement, and siderúrgico plants increasingly adopt DC microgrids for higher efficiency and simpler energy storage integration.
• Power quality challenges: Frequent sags, swells, and harmonics demand front ends that maintain low THD, high PF, and stable DC rails.
• Sustainability and cost pressure: SiC’s lower losses reduce cooling energy and cabinet size, supporting ESG targets and better TCO.

Sicarb Tech delivers turnkey SiC DC power platforms from 3 kW rectifier bricks to 30–100 kW rack modules and 250 kW+ cabinet systems, featuring totem-pole/Vienna front ends, high-frequency isolated DC/DC stages, and intelligent control for resilience and remote management.
