Variable Frequency Drive Industry Trends and Applications
Over the past few years, power electronics technology has reduced VFD costs and size and increased performance through developments in semiconductor switching systems, drive topologies, simulation and control technologies, and hardware and software operation. Variable Frequency Drives (VFDs) are a green energy efficiency device that compares the amount of work or load on the engine to the amount of energy it takes to power the amount of work. It reduces the consumption of surplus energy. Variable Frequency Drive What is the variable frequency drive (VFD)? Variable-frequency drive (VFD) is a type of adjustable-speed drive used in electro-mechanical drive systems that helps to control AC motor speed and torque by varying engine input and voltage. VFDs are used for applications ranging from small devices to massive compressors. Currently, 25% of the world's electrical energy is used by electric motors in commercial applications. Systems that use VFDs can be more effective ...
