What is an autotransformer?

Autotransformer is an electrical transformer containing only singular winding rather than separate primary and secondary winding. The only winding still allows the performance of the same function as the ordinary transformer. In autotransformers, each opposite side of the coil acts as the primary or secondary side, depending on which side of the coil is connected to the load compared to the power supply. Between the two opposite sides, which is drawn from the voltage created by an autotransformer, so that the transformer works so that the transformer works as it works as intended.

The primary function of the transformer is to transform the amount of voltage directed to the circuit by connecting the connection from the power supply to the load at a certain point in the transformer winding. Since the amount of windings or rotation inside the transformer coil determines the amount of voltage released at any point of the winding, the connection can be monitored to the output voltage before the connection is made. For example, if the voltage gets upThe autotransformer is 100V, half of the point or center of the transformer coil allow the output voltage of 50 V. The output voltage of the autotransformer depends directly on the point at which the connection to the circuit is made in the transformer coil.

However, this does not mean that Autotransformers all have every same ability as an ordinary transformer. There are restrictions that accompany autotransformers that do not limit conventional transformers. For example, the insulation provided by a conventional transformer between its individual windings is not available using autotransformers. As a result, the failure of the winding insulation is possible, creating a unified voltage throughout the winding, creating an input of the same as output voltage across the winding.

If the winding inside the autotransformer is in a ratio that allows the output voltage at the end of the winding, the total output voltage at the end of the winding may have the followingOutput voltage larger than input voltage supplied to autotransformers. This is an important variable that you may be aware of when creating a power source for multiple circuits using autotransformers. Connecting the circuit to the end of the winding, which is unable to tolerate the amount of voltage at the end of the winding, may result in damage to the circuit.
