Variable frequency drives (VFDs) save energy, increase the life of mechanical systems, and offer valuable control features in a wide range of building management applications. A new VFD design includes all the advantages of conventional VFDs with the added benefit of low-to-no harmonics in a simple-to-install, cost-effective package. This white paper describes how the Matrix design achieves its added advantages, including helping to achieve IEEE 519-2014 compliance in the overall system design.
