Power Electronics Lab


Power electronics is the application of solid-state electronics to the control, conversion, and conditioning of electric power. It also refers to a subject of research in electronic and electrical engineering which deals with the design, control, computation, and integration of nonlinear, time-varying energy processing electronic systems with fast dynamics.

Power electronics is a broad area. Experts in the field find a need for knowledge in advanced circuit theory, electric power equipment, electromagnetic design, radiation, semiconductor physics and processing, analog and digital circuit design, control systems, and a tremendous range of sub-areas.

Major applications addressed by power electronics include:

Major applications addressed by power electronics include:

  • Energy conversion for solar, wind, fuel cell, and other alternative resources.
  • Advanced high-power low-voltage power supplies for computers and integrated electronics.
  • Efficient low-power supplies for networks and portable products.
  • Hardware to implement intelligent electricity grids, at all levels.
  • Power conversion needs and power controllers for aircraft, spacecraft, and marine use.
  • Electronic controllers for motor drives and other industrial equipment.
  • Drives and chargers for electric and hybrid vehicles.
  • Uninterruptible power supplies for backup power or critical needs.
  • High-voltage direct current transmission equipment and other power processing in utility systems.
  • Small, highly efficient, switching power supplies for general use.

The objectives of the Power Electronics Laboratory course are to provide working experience with the power electronics concepts presented in the power electronics lecture course, while giving students knowledge of the special measurement and design techniques of this subject. The goal is to give students a "running start," that can lead to a useful understanding of the field in one semester. The material allows students to design complete switching power supplies by the end of the semester, and prepares students to interact with power supply builders, designers, and customers in industry.
The laboratory is located in the room no. 5011 in the Electrical Engineering Department, Academic Building- II. The equipment and support have been completely renovated, including an entirely new facility. The laboratory rivals many modern industrial research counterparts in terms of safety and instrumentation. The room includes a set of workstation panels to distribute power throughout the room and special lab benches that are the primary tool for all work. The benches hold rotating machines, dedicated power meters, an instrument rack, a cable rack, and connection panels. Extra instrumentation and equipment are stored in cabinets at the bottom of each bench.
The master circuit breakers in the room have what is called a “shunt trip” mechanism. They can be turned off with a short pulse of ac power. This provides an emergency disconnect capability. It does not affect lights or regular wall outlets in the lab.
