ABOUT THE COURSE
The operational principle of Transformers and Direct Current (DC) Electrical Machines are covered in this course. Both the single-phase and three-phase transformers are analyzed in details considering magnetic circuit design, parallel operation, various connection diagrams, etc.Thereafter, the DC machines are presented starting from their construction, principle of operation, starting, braking and speed control methods. All of the topics are presented in a lucid and interactive manner, such that at the end of this course, students will get a good understating on the aforesaid areas. Assignments with numerical problems are provided on each topic to further improve the understanding and to develop problem solving skills. In some cases, laboratory demonstration is included to give a feel of hands-on-experience. The dynamic simulation of electrical machine using MATLAB/SIMULINK is also included to study the performance during steady state and transients.
