Episode notes
Transformers Get A Software Upgrade
- Solid-state transformers replace passive, old-school copper/iron transformers with controllable power electronics.
- This change gives grid operators real-time monitoring and control over electricity flow.
Semiconductors Replace Windings
- Solid-state transformers use semiconductors like silicon carbide and gallium nitride for frequency conversion.
- They are software-updatable, flexible, and immune to copper price swings that affect legacy units.
Aging Fleet Meets Surging Demand
- Most distribution transformers are decades old and over half are older than 35 years.
- Rising demand from data centers and EV chargers means transformer load could double by 2050.
