Revolutionizing EV Charging: It's Time to Ditch the Isolation Transformer
2025-03-05
The widespread adoption of electric vehicles is hampered by expensive and complex charging infrastructure. This article argues that current EV charging systems use isolation transformers for safety, but this adds significant cost and bulk. The authors propose a new approach called Direct Power Conversion (DPC), eliminating the isolation transformer through double grounding and ground continuity detection, thus reducing costs, improving efficiency, and enhancing safety. This would drastically lower the cost of charging stations, accelerating the transition to electric vehicles.
