Three-phase Variac: A specialized form of auto transformer that allows continuous adjustment of output voltage from zero up to the input voltage.
- Auto transformer design: Uses a single winding that acts as both primary and secondary, unlike conventional transformers with separate windings.
- Variable output: By rotating a brush or contact over the winding, the voltage can be varied smoothly.

Single winding: One continuous coil wound on a laminated core.
- Movable carbon brush: Rotates over the winding to tap different points, changing the output voltage.
- Core: Usually toroidal (circular) for compact design and efficiency.
- Operation: As the brush moves, the effective number of turns changes, varying the voltage proportionally.
