An auto transformer is an electrical transformer with one winding that acts as part of both the primary and secondary winding. The winding can have multiple taps where each tap along the winding corresponds to a different load voltage. However, for best performance, a single tap is highly recommended. The voltage source and the electrical load are connected to two taps, in which one of the taps at the end of the winding is a common connection to both circuits.
