Step-up & Step-down Transformers

Due to the heavy load shedding in countries like Pakistan and India, someone can easily find inverters. While this small Step Down transformer is used to power up the electronics. As the Step Up and Step Down Transformers are one of the most frequently used Electronic Devices, this is why I decided to write a detailed article about the Step Up and Step Down Transformers, and share with you some basic knowledge of how these transformers can be designed. This article only focuses on the designing and calculation of the Step Up and Step Down Transformers. In Step up Transformer primary coil turns are less than secondary coil turns it converts the low primary voltage to a high secondary voltage i. For example, consider a transformer in which the number of turns in the primary winding and that in the secondary winding is If the alternating voltage at the primary of the transformer is V, then the voltage at the secondary of the transformer can be calculated using the following equation.

Step Up and Step Down Transformer Designing with Calculation

A Transformer is a static apparatus, with no moving parts, which transforms electrical power from one circuit to another with changes in voltage and current and no change in frequency. There are two types of transformers classified by their function: Step up Transformer and Step down Transformer. A Step up Transformer is a device which converts the low primary voltage to a high secondary voltage i.

Step Down Transformer

Safety critical assessments and incident investigations are continuing, as per our mandate.

How to Make a Step-up Transformer?

If magnetism can be produced from electricity it was hypothesized by Faraday that electricity can be produced by magnetism. Faraday used an apparatus consisting of soft iron core similar to that shown below. The coil on the left was connected to a battery and the coil on the right was connected to a galvanometer. When the current flows through the left coil connected to the battery a magnetic field is produced. The strength of the magnetic field is increased by the iron core. Although Faraday was not able to produce a current in the left wire, but strangely he noticed that current was produced when the current changed. Faraday concluded that although a steady magnetic field produced no electric current, a change in magnetic field did produce a current.

Equality of voltage and current between the primary and secondary sides of a transformer, however, is not the norm for all transformers. Notice how the secondary voltage is approximately ten times less than the primary voltage 0. What we have here is a device that steps the voltage down by a factor of ten and current up by a factor of ten:. Turns ratio of yields primary: secondary voltage ratio and primary: secondary current ratio. This is a very useful device, indeed.
