ABSTRACT
This article focuses on the specification of variable-frequency drives (VFDs). VFDs are an electrical device that performs a mechanical function for a heating, ventilation, air conditioning process. A cross-discipline assessment is required for a successful specification of VFDs. Motor and distribution-system issues to be considered to successfully install VFDs are discussed.
