Single Phase, Yaskawa partner up on VFD converters

Single Phase Power Solutions has partnered with Yaskawa America to incorporate the latter’s VFD (variable frequency drive) and digital single-phase converters within Single Phase’s engineered power systems. The move was announced in a February 16 press release e-mailed to Electrical Apparatus.

“Application of these proven products enhances SPPS’ capabilities to engineer systems to deliver clean, stable, reliable three phase power from single-phase utility service,” Jim Wahl of SPPS told EA via email. “Given the vast areas where three phase power is not available, and cost-prohibitive to bring in” he continued, the collaboration could be helpful to industry members.

The availability of digital solutions is expected to bolster SPPS’ capabilities to engineer custom designs based on application-specific parameters, the company said in the press release. In many areas of the country, it is prohibitively expensive to extend three-phase power, forcing customers to choose among problematic options such as static or rotary phase converters, or derating three-phase VFDs, which can produce harmful harmonics that can damage sensitive electronics.

The partnership allows Cincinnati-based Single Phase to better design custom power sources to suit site-specific needs, with no harmonics, no reliability issues, and no tuning required.

“We’re excited to partner with Yaskawa and include their Digital Single-Phase Converters in our product offerings,” said SPPS President Drew Abbott.  “Incorporating their best in class technology allows us to add even more performance to our engineered power sources.  We’re seeing more interest in custom packages like VFDs with single-phase converters that allow remote monitoring.  This partnership gives us a more robust toolbox for designing power solutions engineered for specific applications.”.

The partnership with Yaskawa provides substantial benefits, including an IEEE 519 compliant product with total harmonic distortion of less than 10% which reduces installation costs.  Drive sizing is more accurately accomplished, eliminating the need to oversize, thus saving acquisition and operating costs.

Additionally, SPPS manufactures the world’s only large horsepower single-phase motor.  The company offers solutions for agricultural, industrial, municipal, oil & gas, and emerging market applications that need large horsepower output but only have access to a single-phase power line.  They manufacture a range of Belle Motors up to 100 HP as well as their 1-to-3 PowerSource (pictured above) that generates three-phase power from a single-phase line.
