제품 개요 및 2025년 시장 관련성

Silicon carbide (SiC) online UPS converter modules are pre-engineered power stages that integrate SiC MOSFETs/diodes, high-density magnetics, digital control, and advanced thermal management to deliver continuous, double-conversion protection for mission-critical loads. Compared with silicon-based UPS designs, SiC modules achieve higher efficiency at both full and light load, faster transient response, and lower thermal stress—key for Pakistan’s data centers and financial machine rooms facing high ambient temperatures, dusty environments, and unstable mains.

Why 2025 matters for Pakistan:

• Energy and reliability pressures: Data center operators and banks demand 97%+ double-conversion efficiency and near-zero downtime to control OPEX and safeguard services.
• Grid volatility: Frequent sags, swells, and harmonics require robust rectifier/inverter performance with low THD and high PF.
• Space and cooling constraints: Higher power density and lower heat output shrink UPS rooms and reduce HVAC costs, enabling more IT rack capacity in the same footprint.
• ESG and compliance: Improved efficiency supports sustainability goals and aligns with NTDC Grid Code power quality expectations.

Sicarb Tech’s SiC online UPS converter modules cover 10–300 kW per frame (parallelable to multi-MW), featuring totem-pole or Vienna PFC front ends and high-frequency DC/DC + inverter stages. They include protection, telemetry, and hot-swappable mechanics for rapid deployment and maintenance.

일반적인 질문 및 전문가 답변

• Can SiC UPS maintain high efficiency at partial loads?
• Yes. Our designs sustain 96.5–97.5% from 25–100% load with optimized gate timing, magnetics, and PFC control.
• Will low THD hold on distorted Pakistani mains?
• With adaptive harmonic compensation and robust current control, we achieve ≤3% THD across typical distortion profiles.
• Is liquid cooling necessary?
• Not always. Air-cooled frames up to ~100–150 kW are viable; liquid cooling boosts density and reduces noise for larger modules or hot rooms.
• How fast is switchover/bypass?
• Static switch transitions occur within milliseconds; double-conversion topology ensures zero transfer time to the critical load.
• What is the expected ROI?
• Typically 12–24 months via energy and HVAC savings, with additional value from reduced downtime and service calls.
