Auto Transformers are single winding Toroidal Transformers made for voltage step up or step down. Auto Transformers are used in applications where there are no requirements on electrical isolation between input and output windings. Auto Transformers offer a significant size and weight reduction as well as the lower cost. The power rating of an Auto Transformer is calculated as follows :
P = Pout x (Vhi – Vlow) / Vhi
Vhi = Voltage across the high voltage tap
Vlow = Voltage across the low voltage tap
