Phase Technologies is a power electronics manufacturer located in Rapid City, South Dakota. Founded in 1999, Phase Technologies developed the world’s first digital phase converter, called the Phase Perfect® Digital Phase Converter. This was the first major advancement of phase conversion technology in decades. Recognized as the world’s leading manufacturer of phase converter technologies, the company expanded the technology into variable frequency drives (VFDs) in the irrigation, water pumping, HVAC and oil & gas industries.
Specializing in VFDs with Active Front End technology, Phase Technologies produces the only low harmonic, fully regenerative, phase-converting VFD that complies with IEEE 519, the international standard for allowable harmonic levels on utility mains. The company has an extensive product line-up of low harmonic, fully regenerative drives in both three-phase and phase-converting models.

The company operates a certified UL 508A panel shop to integrate our drives into rugged outdoor panels with custom options for applications including irrigation, oil and gas production, and general industrial control. The custom integrations are part of the manufacturing process, not an afterthought.
