Power Electronics and Its Applications
( Prof. A.K. Wahi; Prof. A.K. Kapoor; Dr. R. Mahanty, Mrs Kalpana Chaudhary and Shri S.K.Singh)

As a distinct technology and as an academic discipline power electronics has grown tremendously over the last two decades. Power electronics technology is having impact on our national economy also. A number of industrial units for the manufacture of power electronic converters for applications in different sectors of electrical energy use has been established. These power electronics devices and equipment manufacturers still have to depend upon foreign collaboration. This is not very encouraging for the growth of power electronics technology as the foreign technology given to the developing countries is usually old and never the state of the art. Secondly, it creates a permanent dependency on foreign technology, particularly in the fast changing modern area of technology, to meet the challenges of the coming decades. Expertise in power electronics applications is being continuously developed in the department through advance teaching and research program as well as, through indigenous technology development in joint collaboration with industry. Presently work is going on in the following topics of current interest:

• Switched Reluctance Motor Converters
• Slip Controlled Induction Motor Drives
• Switch Mode Power Supplies (SMPS)
• Energy-system Management
• Resonant Converter/Inverter
• Resonant DC link PWM Inverter
• Vector Controlled AC Drives
• Power Quality Improvement, Active Filters

Electrical Energy Management & Simulation
