transformer (redirected from Auto Transformer)

trans·form·er  (trns-fôrmr) n. 1. One that transforms. 2. A device used to transfer electric energy from one circuit to another, especially a pair of multiply wound, inductively coupled wire coils that effect such a transfer with a change in voltage, current, phase, or other electric characteristic.

transformer  (trns-fôrmr) A device used to change the voltage of an alternating current in one circuit to a different voltage in a second circuit, or to partially isolate two circuits from each other. Transformers consist of two or more coils of conducting material, such as wire, wrapped around a core (often made of iron). The magnetic field produced by an alternating current in one coil induces a similar current in the other coils. If there are fewer turns on the coil that carries the source of the power than there are on a second coil, the second coil will provide the same power but at a higher voltage. This is called a step-up transformer. If there are fewer turns on the second coil than on the source coil, the outgoing power will have a lower voltage. This is called a step-down transformer. Compare converterrectifier

transformer The increase or decrease in the voltage of a signal is related to the ratio of the number of turns of wire in the coils. In the upper transformer, the outgoing voltage is doubled because the secondary coil has twice as many turns as the first. In the lower transformer, the voltage is halved.
