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.

Bishop Jovan (Mladenović)

(1994–2002)

The Divine provision brought the spiritual father of the Monastery Studenica, Bishop Jovan, to continue the work left by the equally most esteemed and humblest spiritual father of the Monastery Hilandar, Bishop Chrysostom.

As an accomplished monastic with the spiritual wealth he attained in the Studenica Monastery, he enriched his flock and clergy. Very soon he gained respect and confidence of his clergy and the faithful.

Bishop Jovan was born in 1950 of father Radojko and mother Stana Mladenović in the village of Dobrace, near Arilje, Serbia. He finished elementary school in his village. At the age of twelve, he went to the Klisura Monasteiy where he remained for one year and then went to the Studenica Monastery. He attended the monastic school in the Ostrog Monastery from 1967 until 1969. He was ordained a hierodeacon in the Studenica Monastery on April 25, 1971. He retained his baptized name of Jovan. Rt. Rev. Vasilije, Bishop of Žiča ordained him as hieromonk in 1973. He graduated from St. Sava Seminary in Belgrade in 1974 and from Theologcial College in Belgrade in 1980.

Notes On Ecumenism

Written in 1972 by St. Abba Justin Popovich, edited by Bishop Athanasius Yevtich, translated from Serbian by Aleksandra Stojanovich, and proofread by Fr Miroljub Ruzich

Abba Justin’s manuscript legacy (on which Bishop Athanasius have been working for a couple of years preparing an edition of The Complete Works ), also includes a parcel of sheets/small sheets of paper (in the 1/4 A4 size) with the notes on Ecumenism (written in pencil and dating from the period when he was working on his book “The Orthodox Church and Ecumenism”; there are also references to the writings of St. Bishop Nikolai [Velimirovich], short excerpts copied from his Sermons, some of which were quoted in the book).

The editor presents the Notes authentically, as he has found them in the manuscripts (his words inserted in the text, as clarification, are put between the slashes /…/; all the footnotes are ours).—In the appendix are present the facsimiles of the majority of Abba’s Notes which were supposed to be included in his book On Ecumenism (written in haste then, but now significantly supplemented with these Notes. The Notes make evident the full extent of Justin’s profundity as a theologian and ecclesiologist of the authentic Orthodoxy).—The real Justin is present in these Notes: by his original language, style, literature, polemics, philosophy, theology, and above all by his confession of the God-man Christ and His Church. He confesses his faith, tradition, experience and his perspective on man, on the world and on Europe—invariably in the Church and from the Church, in the God-man Christ and from Him, just as he did in all of his writings and in his entire life and theologizing.
