What is an autotransformer?

An autotransformer is a type of transformer that has a single winding that acts as both the primary and secondary winding. This winding is operated at different points to provide different voltage levels. Unlike traditional transformers with separate primary and secondary windings, an autotransformer uses a common winding for input and output, which can make it more compact and cost-effective.

The function of a transformer is to change the voltage level of alternating current (AC) in a circuit. It can either increase (increase) or decrease (decrease) the voltage while maintaining the same frequency. Transformers are essential for the efficient distribution and transportation of energy, ensuring that electricity is delivered at appropriate voltage levels for various applications.

What does an autotransformer do?

A transformer works on the principle of electromagnetic induction. When an alternating current flows through the primary winding, it generates a magnetic field. This magnetic field induces a voltage in the secondary winding, which is either higher or lower than the primary voltage, depending on the winding ratio. The relationship between primary and secondary voltages is proportional to the ratio of the number of turns in the primary and secondary windings.

Where may autotransformers not be used?

There are several types of transformers, including power transformers, distribution transformers, isolation transformers, and autotransformers. Power transformers are used in high-voltage transmission networks, distribution transformers are used to step down voltage for consumer use, isolation transformers provide electrical isolation between circuits, and autotransformers adjust voltages. voltage levels with a single winding.

An AC transformer is a device designed to change the voltage of alternating current (AC). It consists of primary and secondary windings and works on the basis of electromagnetic induction. The primary winding receives the AC input and the secondary winding provides the transformed AC output, allowing voltage adjustment based on winding ratio.
