Variable frequency drives are extensively used devices meant for controlling electrical energy utilization at optimum cost. These are also called variable speed drives, adjustable speed or frequency drives, AC drives, and inverters. Previously, valves and slats were used to control the flow of fluids in electric motor drives which were energy intensive. ... Read more
