Auto transformers are a type of electrical transformer that uses a single winding to both step up and step-down voltage. They share part of the winding for input and output, which makes them smaller, lighter, and more economical. They are often used in situations where only a small voltage change is needed, such as adjusting power supply voltage, starting motors, or in audio devices. Their simpler design also results in higher efficiency and less material use. Auto transformers are commonly found in industrial settings, power systems, and testing labs where efficient voltage regulation is important.
