What is the difference between AC and DC?

 There are two types of electrical currents; direct currents and alternating currents. These are the two-ways electricity flows and is simply the movement of electrons through a conductor. The Direct current was first brought to us by Thomas Edison in the 1800s.  Following, the next type of electrical currents to emerge was alternating currents. During the beginning of this “War of The Currents”, Thomas Edison and Nikola Tesla were in a bitter rivalry.

Beginning in the late 1800’s, Thomas Edison and Nikola Tesla were involved in a competition which came to be known as the War of the Currents. The War of the Currents was a series of events related to the introduction of competing electric power transmission systems to the world in the late 1800’s. 

Both Edison and Tesla were able to develop, imagine or create inventions that are utilized in modern factory environments in some capacity even today. When we consider Industry 4.0 as a 4^th Phase of industrial growth, evolution and progress, it is difficult to dispute that both Edison and Tesla contributed to what is essentially the connected manufacturing environment of the modern age.

Thomas Edison is still considered one of the greatest inventors to ever live.

AC and DC are different types of voltage or current used for the conduction and transmission of electrical energy.

AC stands for alternating current. AC Drives are frequency converters designed to control the speed and torque of an electric motor. The speed is controlled by changing the frequency of the electrical supply to the motor.

The types of motors that ac drives control normally operate at constant speed. Enabling the user to control the speed of motor potentially gives the user benefits in terms of process control and energy savings.

DC stands for direct current. DC motor drives are a type of amplifier or power modulator that integrate between the controller and a DC motor.
