What are the applications of AC drive?

  • 2021-08-24 16:46:04

Drives are widely used in manufacturing industries to regulate and control rotating equipment such as fans, conveyors, machine spindles, and pumps, which are used in production processes. AC drives are widely used in process industries to increase the efficiency of equipment. It controls the speed of electric motors according to the process needs, typically reduces energy consumption by 35-40%.


However, the bulk of the load of an energy intensive industry is driven by High Voltage / High Power AC motors. With the invent of High power transistor devices the current trend is to use Medium Voltage (MV) AC drives for such applications where the magnitude of savings in high.


Energy intensive industries such as Metal, Cement and Power have started using MV Drives for controlling Medium Voltage Motors.


VFDs are now fully function driven, able to compensate for load changes, more intelligent to understand the frequency conversion for speed with high precision, easy to form a closed-loop control and component health monitoring . Also the power handling capacity is changing from AC-DC-AC to AC-AC without storage device in between, this improves the reliability and performance of drives.


Facing challenges from different application areas, the variable speed drive are constantly upgrading and developing into application-specific algorithm, feature rich , easy to operate, versatile, fully function driven software programs. High torque and 4 quadrant applications are being handled by AC drives more intelligently with the advent of software and built-in application algorithm. This gives flexibility to user for easily configuring the drive for his application without much complexity.


Due to technological advancements in semiconductor devices such as insulated gate bipolar transistors (IGBTs), MV drives are increasingly used in Petrochemical, Mining, Steel and Metal, Transportation industries, among others, to conserve electrical energy, increase productivity and improve product quality. Going forward, AC Drives would replace the use of DC Drive system and contactors in motor control centres. Also, the high power high voltage drives will replace the use of inefficient damper and valve control system. This will give reliability of operation coupled with energy saving.
