What is a transformer with a higher secondary voltage than primary voltage called?

A transformer that has a higher secondary voltage than primary voltage is known as a step-up transformer. This device operates on the principle of electromagnetic induction and is designed to increase voltage from the primary coil to the secondary coil. When electricity passes through the primary winding, it generates a magnetic field that induces a higher voltage in the secondary winding.

This functionality is crucial in various applications, especially in power transmission, where electricity needs to be transmitted over long distances. By stepping up the voltage, the transformer minimizes energy loss due to resistance in electrical lines, allowing for more efficient delivery of power.

Other types of transformers, such as a step-down transformer, serve the opposite purpose by reducing voltage. Voltage converters and power inverters serve different roles in electrical systems as well, focusing on converting voltages or direct current to alternating current, and are not specifically designed for the increase of voltage as required in this context.
