    Autotransformer: Working Principle and Advantages

    Autotransformer refers to a transformer whose windings are primary and secondary on the same winding, with the primary and secondary windings directly connected in series and self-coupled. According to the structure, it can be further divided into adjustable pressure type and fixed type. A regular transformer transfers energy through electromagnetic coupling between the primary and secondary coils. There is no direct electrical connection between the primary and secondary coils, while an autotransformer has a direct electrical connection between the primary and secondary coils. Its low-voltage coil is a part of the high-voltage coil. ATO online store will explain how autotransformers work and their advantages in power systems and electronic devices.

    What is an Autotransformer Used for?

    An autotransformer is a special type of transformer in which the primary and secondary windings are on the same winding. The primary and secondary windings of this transformer are directly connected in series and self-coupled. Autotransformers are widely used in many fields. Next, we will mainly introduce the specific applications of autotransformers in eight aspects, including power systems, industrial automation, test equipment, audio processing, communication systems, railway transportation, measuring instruments, and aerospace.

    What are the Applications of Autotransformer?

    An autotransformer is a type of electrical transformer where a single winding is used to serve as both the primary and secondary winding. It differs from a standard transformer, where the primary and secondary windings are separate and not electrically connected. Autotransformers have many uses in our life. In the following, ATO industrial automation will introduce the application of autotransformer.

    How to Test a Transformer?

    Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Whether troubleshooting a transformer or replacing one, knowing how to test a transformer is an integral part of the process. The three primary tests used to determine the condition of a transformer are the open-circuit test, short-circuit test, and measurements of winding resistance. In this atricle, ATO industrial automation will introduce 3 methods of testing transformer.

    What are the Functions and Features of Autotransformers?

    An autotransformer is a special transformer with primary and secondary without insulation. In short, it means that its primary and secondary windings are on the same winding, i.e., a transformer with only one winding, which means it is a special transformer with a common set of coils for output and input. When the autotransformer is used as a step-down transformer, part of the line turns are taken out from the winding as the secondary winding, and when the autotransformer is used as a step-up transformer, the applied voltage is only added to part of the line turns of the winding. Because DC power cannot be directly stepped up, it needs to go through electronic and other components.

    Difference Between Autotransformer and Isolation Transformer

    Autotransformers and isolation transformers are two different forms of transformers that work on the same principle. Both use an energy conversion between the alternating magnetic field and the alternating current in the coil to convert the voltage. So what's the difference between them? The following article lists six major differences between autotransformers and isolation transformers.
