![]() ![]() The voltage and currents in the primary and secondary windings are linked to the number of turns by the following relation: Read our article on electrical transformers for more information on transformer’s working and construction.įigure 2: Transformer windings (A and B) on a magnetic core (C) An alternating magnetic flux produces a corresponding voltage in the secondary winding initiating a current flow. A portion of this flux links with the secondary side through mutual induction. As the current is alternating in nature, it creates a fluctuating magnetic flux. An alternating current passed through the primary winding creates a magnetic flux across the primary coil. Transformers are commonly used in instrumentation, telephone, and control circuits.Ī single-phase transformer consists of two windings, namely primary windings (Figure 2 labeled A) and secondary windings (Figure 2 labeled B), wound on a magnetic core (Figure 2 labeled C). Voltage and current conversion in a transformerĪ transformer is an impedance transformation device that facilitates the maximum power transfer from the input circuit to the output device.
