autotranszformátor
An autotransformer is a type of electrical transformer that uses a single tapped winding instead of two or more separate windings, as is found in conventional transformers. This single winding acts as both the primary and secondary coil. The windings are electrically connected, and power is transferred through both electromagnetic induction and electrical conduction.
Autotransformers are commonly used for voltage regulation and for starting electric motors. Because they use less
A key characteristic of an autotransformer is that a portion of the winding carries both the primary
