Slobodan Ćuk

BSEE, Belgrade University, Yugoslavia, 1970
MSEE, University of Santa Clara, CA, USA 1974
Ph.D., Caltech, CA, USA, 1976

Dr. Slobodan Ćuk was a full-time Professor of Electrical Engineering at the California Institute of Technology until January 1, 2000. During that time, more than 30 students obtained their Ph.D. degree in Power Electronics under Dr. Ćuk's guidance. Many of them are now leading researchers and/or Professors of Power Electronics in the U.S. and abroad.

Dr. Ćuk won a coveted IR*100 Award in 1980 from the Industrial Research Magazine for the invention of a new and patented switching converter topology and several of its extensions, which are now known as the ĆUKonverter technology. For the invention of Integrated Magnetics and expediting the development of switched-mode power converters, Dr. Ćuk obtained the prestigious 1991 Edward Longstreth Medal from the Franklin Institute, which was for the first time in its 100 years history awarded to researchers in Power Electronics. His publications include over 100 scientific papers in the Power Electronics field and a three-volume book on Advances in Switched-Mode Power Conversion.

Over a span of 20 years, Dr. Ćuk has taught a number of public and in-house courses in the United States, Europe and Far East, and gave a number of tutorial seminars at leading Power Electronics conferences throughout the world. These courses and seminars have been attended by over 4,000 Power Electronics specialists.

In 1979, Dr. Ćuk founded TESLAco with the charter to apply the basic research results developed at Caltech to practical commercial and military designs. He holds over 30 patents related to new switched-mode power conversion concepts.

He received Franklin laureate award for pioneering and expediting the development of integrated magnetics and switched-mode power conversion.

Abstract

The principal objective of this work on modeling and analysis of switching dc-to-dc converters and regulators is to obtain a linear model (either through state-space or linear circuit description), subject to appropriate restrictions, for the inherently nonlinear power state in which the dc conversion is accomplished. A general unified approach to modeling and analysis of switching dc-to-dc converters is developed which is directly applicable to any dc-to-dc operating in either of two conduction modes (continuous or discontinuous inductor current), and which results in a final dynamic linear model either in terms of state-space equations or in terms of their corresponding linear circuit models. In particular, in Part I this analysis technique, called state-space averaging, is applied to the continuous conduction mode of converter operation, while in Part II appropriate extension of the method to the discontinuous conduction mode is made. In each case, the culmination of modeling and analysis is achieved in the development of canonical circuit models which represent any such converter regardless of its detailed configuration.

The insights that emerge from the general state-space modeling approach (Parts I and II) lead in Parts III and IV to the design of new converter topologies through the study of generic properties of the cascade connection of basic buck and boost converters. This study paves the way in Part IV to the discovery of a new switching converter based upon capacitive rather than the usual inductive energy transfer. The new converter is shown to have substantial advantages over the conventional converters in its class in efficiency, performance, and also in size and weight.

Bothe the state-space averaged models and their corresponding circuit realizations provide the circuit designer with a powerful tool for analysis of existing converters as well as for synthesis of new converter topologies.

Slavoljub Slavko Vorkapić

Slavoljub Slavko Vorkapić (Serbian Cyrillic: Славољуб Славко Воркапић; March 17, 1894 – October 20, 1976), known in English as Slavko Vorkapich, was a Serbian-American film director and editor, former Chair of USC Film School, painter, and a prominent figure of modern cinematography and film art.

Slavoljub Vorkapić was born on March 17, 1894, in the small village of Dobrinci near Ruma in the Syrmia region, at the time part of the Kingdom of Croatia and Slavonia of the Austro-Hungarian Empire (now Serbia). His father Petar, the town clerk, insisted that young Slavko should be well-educated.

Sebastian Press Mission Statement

Welcome to the Sebastian Press Publishing House of the Western Diocese!

Founded in 2006 and named in honor of a first American born Orthodox priest, Fr. Sebastian Dabovic, a pioneer of the Orthodox Church in the West, Sebastian Press is one of the largest and most active publishers of Christian Orthodox publications on the West Coast.

Our hard working staff seeks to fruitfully enrich and deepen the faith of Christians from all over the world with a variety of titles, embracing a diversity of Orthodox Traditions, while also presenting the works of Serbian theologians.

Sebastian Press is building its reputation for promoting high quality theological, historical, ecclesiastical, spiritual, hagiographical, iconographical, philosophical and patristic writings in its repertoire. Also, due to growing demand, we are giving special attention to the publishing of new titles for children, teens, and families, including video and audio programs.

The primary mission of Sebastian Press is to motivate and inspire its readers to seek a deeper union with the God-Man, through the written word of Orthodox Christian material, both on the scholarly and popular level, and to give glory to the life-giving Trinity.

Sebastian Press is located in Los Angeles, at the headquarters of the Western Diocese of the Serbian Orthodox Church.
