VFI

VFI is an acronym that can refer to several terms across different fields. There is no single standard definition, and the intended meaning depends on the context in which it appears.

In power electronics and motor control, VFI is sometimes used to denote Variable Frequency Inverter, a device that adjusts the frequency (and often the voltage) of an electrical supply to control motor speed. In many cases, the term Variable Frequency Drive (VFD) is used instead, with VFI appearing mainly in certain manufacturers’ literature.

In finance and investment, VFI has been used as part of organization or program names and may stand for different phrases depending on the institution, such as venture funding initiatives or fund-specific identifiers. The definition is not standardized.

In information technology and networking, VFI has been used to refer to concepts such as Virtual Function Interface or Virtual Forwarding Interface, terms associated with virtualized network services and interfaces. The exact meaning varies by vendor and standard setting.

Other uses include nonprofit, academic, or industry groups that adopt the acronym as part of their name, with each group assigning its own expansion. Because the meaning of VFI varies by context, it is essential to rely on the surrounding text or explicit definition to determine what VFI stands for in a given document.
