Power semiconductors are taking on a central role as AI data centers move from 800V high-voltage input down through multiple power-conversion stages to the ultra-low voltages used by chips. After the post-pandemic inventory correction, industry players say power semiconductors have shifted "from a supporting role to the lead" under the new AI high-voltage direct current (HVDC) power architecture.

As hyperscale cloud providers and enterprise customers race to build increasingly powerful artificial intelligence infrastructure, power delivery and energy efficiency are emerging as critical constraints. Industry analysts expect AI rack power requirements to exceed 1 MW per rack in the coming years.
