A 1-phase to 3-phase converter, also known as a single-phase to three-phase converter or single-phase to polyphase converter, is a device that converts single-phase electrical power into three-phase electrical power. This conversion is required when there is a need to power three-phase equipment or machinery from a single-phase power source.
Three-phase power systems are widely used in industrial and large-scale commercial applications because they offer advantages such as higher efficiency, balanced power distribution, and the ability to handle heavy loads. However, in some cases, the available power source may be single-phase, especially in residential areas and smaller commercial buildings.
Static Phase Converter: A static phase converter uses electronic components like capacitors and resistors to generate the third phase. It provides a pseudo-third phase to power the three-phase loads, but it may not be as efficient as a true three-phase supply.
An auto transformer is used if single phase VAC inputs are different than the three phase outputs.
