Infineon Expands XHP 2 CoolSiC MOSFET Power Module Portfolio

Why It Matters

The expanded XHP 2 line gives system designers a more efficient, compact solution for next‑generation wind, solar and battery‑storage converters, accelerating the shift to higher‑voltage renewable grids.

Key Takeaways

• 2300 V CoolSiC MOSFET modules support up to 1500 V DC‑link
• On‑resistance ranges from 1 mΩ to 2 mΩ, improving efficiency
• Symmetrical switching enables easy paralleling in large converters
• Demonstrated 300 kW/L power density in wind‑power test

Pulse Analysis

Silicon‑carbide (SiC) power devices have become a cornerstone of the clean‑energy transition, offering lower losses and higher temperature tolerance than traditional silicon. Infineon's latest XHP 2 CoolSiC MOSFETs extend this advantage to the 2300 V class, a segment previously dominated by IGBT solutions. By delivering on‑resistance as low as 1 mΩ and robust isolation ratings, the new modules enable designers to push DC‑link voltages toward 1500 V, a trend driven by the need for higher power throughput in wind turbines and utility‑scale solar inverters.

The technical refinements translate into tangible system benefits. In a wind‑power demonstration, the modules achieved a power density of 300 kW per liter, while battery‑storage tests recorded semiconductor losses under 0.7 % of output power. Such figures reflect the combined impact of reduced switching losses, symmetrical turn‑on/turn‑off behavior, and the optional pre‑applied thermal interface material that streamlines heat management. Engineers can now opt for higher switching frequencies without incurring excessive harmonic distortion, shrinking converter footprints and lowering overall capital costs.

Market implications are significant. As utilities and independent power producers chase higher efficiency to meet decarbonization targets, the availability of a standardized, high‑voltage SiC platform simplifies product development cycles. Competitors are racing to match Infineon's performance claims, but the company’s .XT interconnection technology and proven reliability give it a competitive edge. Adoption will likely accelerate in regions with aggressive renewable mandates, positioning the XHP 2 portfolio as a catalyst for the next wave of high‑voltage, high‑efficiency power conversion equipment.
