What Is Auto Transformer?

  •   Auto Transformer refers to a transformer in which the primary and secondary windings are on the same winding, and the primary and secondary windings are directly connected in series. According to the structure, it can be divided into adjustable pressure type and fixed type. Self-coupling refers to electromagnetic coupling. Ordinary transformers transfer energy through the electromagnetic coupling of primary and secondary coils. There is no direct electrical connection between the primary side and the secondary side. The primary and secondary sides of the Auto Transformer have a direct electrical connection. Its low-voltage coil is part of the high-voltage coil. Protection equipment such as Auto Transformer is also used for the protection equipment of communication lines.

      Advantages of Auto Transformer:

      cheaper and more efficient

      Less leakage inductance between primary and secondary, so fewer losses

      Simple construction for OEM

      Smaller footprint for the same VA rating

      The main purpose of an Auto Transformer is to adjust the voltage of the transmission line, which can be used to transform the voltage. The Auto Transformer has only one winding and can automatically adjust the voltage according to the load. These transformers require AC power to function properly and cannot use DC power.
