What is the difference between Step-Down and Step-Up Transformer

Posted by servostabilizer on February 3rd, 2018

Transformers are the most influential device which is used to transform electrical energy from one device to another. So, you will not require a direct electrical connection and the operation of mutual induction is carried between two windings of the transformer. These devices are highly demanded in the market to serve the industries with the complete electricity protection. Transformer comes in different ranges such as Auto Control, Three Phase, Isolation, Rectifier, Step Down, Step Up and Special Purpose Transformers also build in order from various others. Every transformer works differently but all of them provide a constant power supply.  

Among this wide range of transformers, Step-Down and Step-Up transformers work as per their names.  A Step-down has the core function of regulating the high voltage into the low voltage as per their requirements of devices. In other hands, a Step-up does just opposite of step-down transformer. Hence, both devices are manufactured same but the difference lies in their working process. These devices can be switched easily, so the best part is that any of them can work as step up or step down transformer depends on the energy flow direction. Let's see the difference between both types of transformers.       

Difference between Step-Down and Step-up Transformers:

1. Step Down Transformers:

•  It has two windings as other variants i.e. primary and secondary, the secondary winding has the fewer turns as the primary which means primary side would have lower current value.

•  The main difference between the voltage requirement and output is stepped it down for the greater efficiency.

•  Step-Down Transformer converts the high voltage output into the low current, as many devices demand a certain amount of power.

•  Generally, it is designed to provide low voltage value which is suitable for different electronic equipment. For an instance, the daily used battery charges have demands for the low power supply so it requires a Step-down transformer.

2. Step Up Transformers:

•  A step-up transformer has iron core primary winding with fewer turns and the second one was around 10 times more turns, which helps to provide a high voltage.

•  Step-Up Transformers are used widely in the various electronics as well as electrical applications for the better performance while operation.

•  With this device when the input voltage is actually lower than its output, it gets employed for the stepping up the input and provides the required output with the constant supply for the connected applications.

If you are going to buy a transformer for your residential or commercial use, it is recommended to talk with the expert before making your decision.
