For single-phase transformers:

Single-phase, single-winding: The transformer has only one winding, which facilitates the conversion of input and output currents.

Single-phase, two-winding: The transformer has two windings, referred to as the high-voltage winding and low-voltage winding, used for input and output current transformation.

For three-phase transformers:

Three-phase, three-winding: The transformer comprises three windings, typically known as the high-voltage winding, medium-voltage winding, and low-voltage winding. This output configuration is suitable for applications requiring multiple voltage transformations.

Auto-transformer: Also known as an autotransformer or self-coupling transformer, this is a special type of three-phase transformer with only one shared winding. It is utilized for specific applications.

The choice of transformer output configuration in practical applications is determined by the specific requirements of the power system and circuit design. Different output configurations are applicable to varying power capacities, voltage transformations, and specific application scenarios.
