The EVFD system is defined as the entire group of components and accessories needed to absorb power at a fixed voltage and frequency from the point of common coupling, and to provide power with a selected voltage and frequency to an electric machine. In the case of a power recovery system, it refers to that which is needed to deliver power at a fixed frequency and voltage to the point of common coupling, having absorbed power at a variable frequency and voltage.

The efficiency can be measured across the entire EVFD system, including all accessories, the cooling system, input and output filters, power factor correcting capacitors, and inductors.
