How solid-state transformers could help power the AI boom
Solid-state transformers represent an upgrade to conventional transformer designs that have remained largely unchanged for a century. These new devices combine magnetic components with high-power semiconductors, making them more compact and enabling better control of electricity flow. While still in development and unable to fully replace the largest traditional transformers used for long-distance transmission, solid-state versions could alleviate supply constraints and improve grid efficiency by reducing electricity loss as heat during transmission.
Key points
- Solid-state transformers use semiconductors and magnetic components for compact design
- More efficient electricity transfer compared to conventional copper-wire transformers
- Critical for supporting grid demands from growing AI data centers and EV adoption
- Can't yet replace largest transformers for high-voltage long-distance transmission
