- Electrical machines: The electrical machines deal with the energy transfer either from mechanical to electrical form or from electrical to mechanical form; this process is called electromechanical energy conversion. If the translation is from electricity to mechanical power, then the machine acts as a motor. On the other hand, an electric generator converts mechanical energy into electricity. The moving parts in a machine can be rotating or linear. They are widely used in different industries, such as machine tools, aerospace engineering, autonomous power engineering, etc.
- Power Electronics and Drives: Power electronics is a rapidly developing subject. It is all about controlling the flow of electrical energy by switching electronic circuits. The technology which is behind the concept of power converters, power inverters, machine drives, switching power supplies, etc. is the power electronics.
- Control of electrical vehicle and energy management: Fossil fuels that meet most of the energy needs are decreasing day by day. The accelerated use of fossil fuels such as oil, coal, and natural gas in the world, primarily in the 20th century, has a significant impact on the environment. The effects, such as ozone depletion, acid rains, and global warming, may make the world difficult to have a pollution-free environment. The internal combustion motor vehicles are one of the leading causes of environmental contamination due to carbon emissions. Therefore, the vehicle manufacturing is shifting from oil-based use to cleaner and more eco-friendly vehicles called electric vehicles (EVs). Electric vehicles provide mobility by using the electrical energy obtained from the battery to drive the electric motor. Therefore, control and energy management is one of the significant barriers and becoming a significant market player in EVs.
