A converter in an electrical circuit primarily functions to change direct current (DC) to alternating current (AC). This is essential because many electronic devices operate on AC, while some power sources, like batteries, provide DC. The conversion allows devices designed for AC to be powered by a DC source, providing versatility in various applications, such as in renewable energy systems where solar panels generate DC electricity.

The role of a converter is significant in modern electrical systems. Without it, the use of DC power sources would be limited, and many appliances would not operate efficiently. Additionally, this conversion process can involve technologies such as inverters, which are widely used in solar power systems and uninterruptible power supplies (UPS).

While other functions mentioned, such as regulating voltage levels and protecting circuits from overload, play essential roles in circuit design and safety, they are typically associated with devices like voltage regulators or circuit breakers, not specifically converters. Hence, the primary function of a converter is accurately captured in the choice that states its role in changing direct current to alternating current.
