A transformer is a device that is designed to work with alternating current (AC) voltage. It consists of two coils of wire, called the primary and secondary windings, wrapped around a common magnetic core. When an AC voltage is applied to the primary winding, it creates a changing magnetic field in the core, which in turn induces a voltage in the secondary winding.
However, a transformer cannot be used to directly raise or lower the voltage of direct current (DC). This is because a DC voltage does not create a changing magnetic field in the core, which is required for the transformer to work.
To change the voltage of a DC source, a device called a DC-DC converter or voltage regulator is used. A DC-DC converter uses electronic components such as transistors and capacitors to switch and filter the DC voltage, creating a new DC voltage with a different level.
There are different types of DC-DC converters, including buck converters, boost converters, and buck-boost converters. Each of these types has its own characteristics and is used for different applications, such as power supplies for electronic devices or electric vehicles.
