Infineon introduces 27 kW three-phase PSU solution for next-generation AI server power architectures - TimesTech

Infineon's real play isn't shipping a PSU module—it's monetizing automotive power-semi IP for a second time in data centers. A 27 kW three-phase architecture shatters the legacy 5 kW-per-rack ceiling, forcing upstream SiC/GaN devices past 1200 V and compelling facilities to migrate from single-phase 220 V to three-phase 400 V busbars. The entire power-electronics stack gets re-sequenced. On compliance, the EU's CBAM carbon tariff is already adding 3-5% to Infineon's German and Italian fab costs, while back-end packaging remains tethered to OSATs in Taiwan, China. Any export-control escalation fractures lead-time commitments. Competitively, MPS and Delta Electronics will likely ship comparable SKUs within two quarters, but Infineon's moat lies in transplanting IGBT-module reliability engineering into telecom-grade power delivery—something pure-play data-center vendors can't replicate overnight. Over 12-24 months, 800 V DC bus architectures will displace today's AC-DC-DC topologies. The automotive-to-datacenter second curve for power-semi makers is now structural. If Infineon locks into NVIDIA's next-gen reference design, its valuation re-rates from cyclical to platform.
