Step Up And Step Down Transformer Circuit Diagram

The transformation ratio of a transformer will be equal to the square root of its primary to secondary inductance l ratio.
Step up and step down transformer circuit diagram. The secondary output voltage is higher than the input voltage. These transformers are used to convert high voltage primary supply to low voltage secondary output. The step down transformer is shown in the figure below. The voltage turn ratio determines the magnitude of voltage transforms from primary to secondary windings of the transformer.
Step up transformer extends the voltages from 220v 11kv or above whereas step down transformer reduces the voltages from 440 220v 220 110v or 110 24v 20v 10vetc. They are used between the power generator and the power grid. A transformer designed to reduce the voltage from primary to secondary is called a step down transformer. Transformers are most commonly used for increasing low ac voltages at high current a step up transformer or decreasing high ac voltages at low current a step down transformer in electric power applications and for coupling the stages of signal processing circuits.
The voltage turn ratio of the step down transformer is 2 1. The same transformer can be used as a step up or a step down transformer. Transformers can also be used for isolation where the voltage in equals the. Step down transformer is made up of two or more coil wound on the iron core of the transformer.
