Power Electronics: Topologies, Magnetics

and Control

by Professor Slobodan Ćuk

Tutorial

The System Technology (popularly known as converter topologies, magnetics and control) is the cornerstone of the modern Power Electronics for the last 50 years. Dr. Ćuk has pioneered several new switching methods which led to a number of novel converter topologies covered in Advanced Methods and Topologies.

Basics of Topologies, Magnetics and Control

This part is a tutorial of the material Dr. Ćuk has taught as a two-quarter Power

Electronics course at California Institute of Technology (Caltech), Pasadena for

over 25 years. This course was also taken by over 5,000 Power Electronics

specialists who attended his public and in-house courses world-wide. The

detailed synopsis of that course is described in the enclosed 3-page brochure.

Last section expands on that knowledge to introduce new switching methods and

novel converter topologies.

Magnetic BH Loop Demonstrations

The tutorial uses the video demonstration of the BH loop properties of ferrite

magnetics materials on one scope and on another scope the driving voltage and

resulting current waveforms to relate electrical and magnetic properties and

demonstrate core saturation and the core loss properties. The videos were

generated on a custom designed BH loop tester with 1MHz bandwidth (see

enclosed brochure).

Advanced Switching Methods and Topologies

The conventional converter topologies are analyzed and the sources of their deficiencies are established. This, leads to the new switching methods and the corresponding novel switching converter topologies which are overcoming all these deficiencies. Several examples of the new switching methods and topologies will be introduced. Live Demonstrations of Simulations

The performance of several new converters is illustrated throughout tutorial by

live demonstrations of salient waveforms generated on site via a state-of-the-art

simulation program PLECS from PLEXIM (www.plexim.com).
