Step-Up Transformer Simulation

A step-up transformer that increases the voltage from the primary winding to the secondary winding. The secondary winding consists of more turns than the primary winding. Step-up transformers are widely used in inverter and booster applications that convert low voltage to the desired high voltage.

Circuit Diagram of Step-Up Transformer

Input AC voltage is applied to the primary winding. Primary winding has fewer turns than secondary winding. Secondary winding acts as an output.

Simulation of Step-Up Transformer

The simulated transformer was constructed with fewer turns in the primary winding than the secondary winding. An input AC voltage is applied to the primary winding. An output EMF is induced at the secondary transformer.

Here, green-colored windings are primary winding, and red-colored windings are secondary winding.

Input Parameters for Step-Up Transformer

We can derive the property of a step-up transformer by applying number of turns in secondary coil greater than number of turns in primary coil.

So,

Np < Ns , for step-up transformers

By following the rule of step-up transformer, let’s apply Np = 20 turns and Ns = 100 turns with input AC voltage of 10 volts.

Step-Up Transformer Simulation Result

In the following graph, the green-colored plot refers to the voltage applied at the input primary winding, and the red-colored plot refers to the output voltage obtained at the secondary winding.

The sine wave indicates that the applied current is alternating current (AC).

We are applying 10 volts at the primary winding (Vp = 10 volts). Since it is a step-up transformer, the voltage induced at the secondary winding is 50 volts, according to the calculation given below.

Step-Up Transformer Calculation

We know that the voltage in the secondary coil is Vs. By applying the equation (2),

[Tex]{V_{s}} = \frac{N_{s}}{N_{p}}*V_{p} [/Tex]

When Vp = 10 V , Np = 20, Ns = 100 .[Tex]V_{s} = \frac{100}{20}* 10 [/Tex]Vs = 50 Volts

Step-Up Transformer Result

Here, the applied voltage is 10 volts and the output voltage is 50 volts. Therefore, voltage is increased. Hence, the step-up transformer is proven.

The transformer is the simplest device that is used to transfer electrical energy from one alternating-current circuit to another circuit or multiple circuits, through the process of electromagnetic induction. A transformer works on the principle of electromagnetic induction to step up or step down voltage. The transformer either increases AC voltage (Step-up transformer) or decreases AC voltage (Step-down transformer).

A transformer which is normally utilized in the transmission and distribution of alternating current power is a voltage control device. Transformers are used for a wide range of purposes, including increasing the voltage from electric generators to enable long-distance transmission of electricity and decreasing the voltage of conventional power circuits to run low-voltage devices like doorbells and toy electric trains.
