VFD AC Drives

VFD AC Drives are the electronic controlling devices that are used for producing electrical signals of variable frequencies. These are used in conjunction with AC motors to achieve different speeds of the rotors. They are installed with a series of high performance and sensitive electronic components such as diodes, capacitors, and transistors etc. for the functioning of these devices. VFD AC Drives works by converting the voltage signal twice first from AC to DC then after filtering it with the capacitor again transforms it back to the alternating forms and change the frequency with the help of switching equipments. These are also capable to control the ramp-up and ramp-down of the power drives during start and stop respectively.
