What is the function of a phase converter?

A phase converter serves a critical function in industrial and commercial settings where three-phase electric power is required but only single-phase power is available. It enables the operation of three-phase motors and other equipment by converting the single-phase supply into three-phase power, thus allowing equipment designed for three-phase operation to work efficiently.

Three-phase systems are often preferred for their ability to deliver more power and smoother operation than single-phase systems. By using a phase converter, users can expand their operational capabilities and utilize more advanced and powerful machinery without the need to upgrade their entire electrical supply infrastructure.

This capability is essential for many applications, especially in manufacturing and heavy industry, where three-phase motors are common due to their advantages in efficiency and performance. The other options do not accurately describe the primary function of a phase converter, as they relate to different aspects of electrical systems and motor operation.
