INDUSTRIAL DRIVES:

Electrical drive systems have a vital role in savings of energy. These systems are a central part of automation systems & account for two-thirds of electrical energy that is consumed in industry.

Industrial drive technology has two distinct groups. The first group consists of electrically driven machines that need position control. This group involves such as machine tools, packaging machines & measuring machines in which precision in movement is needed. 

The second group includes all the applications in which a fluid acquires movement by pumps & fans. In this situation, the variable speed drives enables adjustment of the flow to the process requirements. 

Electronic speed control raises the entire efficiency as compared to the classic flow control methods such as bypassing & throttling and.

More efficient motor technology such as reluctance motors & permanent magnet synchronous motors can be applied with the use of an inverter.  These types of drives may be implemented in a range of power from Watts to Megawatts.

Almost all the static converters used for electrical drives which are used in these days utilize a combination of DC-link, Output inverter &Input rectifier. 

In the low power range when power factor correction is compulsory in number of applications. Power factor correction circuits may be designed with the use of using discrete IGBTs as well as diodes.
