Advantages of auto-transformer over a two-winding transformer:
- More efficient for the same VA rating
- Smaller in size
- Require less copper in their construction
- Cost is less compared to double wound transformers of the same VA rating
- Core and copper losses are lower due to less resistance and leakage reactance giving a superior voltage regulation than the equivalent two winding transformer
