A converter is a device or software that changes one form of energy, signal, or data into another. For example, a power converter transforms electrical energy from one voltage level to another, making it suitable for different devices. Similarly, a data converter can change analog signals into digital format, allowing computers to process the information. Converters are essential in various applications, including electronics, telecommunications, and renewable energy systems. In renewable energy, a solar inverter acts as a converter by changing the direct current (DC) produced by solar panels into alternating current (AC) for use in homes and businesses.
