Transformers

Inductors, tap changing transformer, two- and three-winding transformers

Increase or decrease AC voltages using transformers. Regulate voltage by varying the turns ratio using a tap-changing transformer.

Featured Examples

Tap-Changing Transformer for Automatic Voltage Regulation

Use a single-phase tap-changing transformer to control the voltage across an RLC load. The system contains an AC voltage source that generates a 60 Hz sine wave (located on the left-hand side of the circuit). The root-mean-square value for the voltage generated by this source is 120 V (reference voltage).
