Variable Frequency Drives and Power Factor
IEEE Transactions on Industry Applications, 1985Variable frequency drives are being used in many applications which were previously fixed speed induction motor applications. The predominant ones are centrifugal pumps and fans where substantial energy savings can be realized with adjustable speed operation.

Efficiency of Introduction of Variable Frequency Drive
2020 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon), 2020The problem of energy conservation is currently very relevant. Analysis of the structure of electricity losses shows that 90% is consumed by electricity, the main consumer of electricity is an electric drive (about 70%), it has a great potential for energy saving.

Fuzzy Logic Controlled Variable Frequency Drives
2018In this paper, a fuzzy-based PWM controller has been proposed for performance and efficiency enhancement in variable frequency drives (VFD). The VFDs are used for controlling operation of induction motors which are generally nonlinear in nature. The nonlinear loads are major cause of harmonics in the power supply and needs attention.
