A variety of commercial and industrial electrical equipment require three-phase power. Electric utilities typically do not install three-phase power because it costs significantly more than a single-phase installation. Rotary phase converters, static phase converters and phase converting variable frequency drives (VFD) generate three-phase power from a single-phase source. However, these technologies have serious limitations, which motivated Phase Technologies, LLC to develop the Phase Perfect® digital phase converter. This patented technology overcomes limitations of earlier phase converter designs and is an affordable alternative to utility installed three-phase power.
A Phase Perfect® digital phase converter provides excellent power quality under all load conditions. The Phase Perfect® operates with near unity power factor and essentially no harmonic distortion of the input while supplying balanced undistorted output voltage. It can safely power virtually any three-phase load within its rated capacity. Three-phase equipment such as submersible pumps, center-pivot irrigation systems, machine tools, sawmills, elevators, HVAC equipment, and CNC equipment are powered easily and reliably. Even when three-phase transmission lines are nearby, installing three-phase service is not cost justified in many small to medium-sized applications. In these cases, Phase Perfect® offers an affordable alternative source of three-phase power.
