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).
