Synopsis

This book is the third in a series of four devoted to POWER ELECTRONIC CONVERTERS: The first of these concerns AC to DC conversion. The second concerns AC to AC conversion. This volume examines DC to DC conversion. The fourth is devoted to DC to AC conversion. Converters which carry out the DC-DC conversion operate by chopping the input voltage or current: they are called choppers or switch-mode power converters. Their operating frequency is not imposed by either the input or the output, both of which are at zero frequency. A frequency which is much greater than that of the industrial network can be chosen, provided that suitable configurations and semiconductor devices are used. This is the first difference compared to the rectifiers and AC-AC converters, analyzed in the previous volumes and which often operate at the industrial network frequency. The second difference concerns the commutation mode. Choppers operate in forced commutation. The beginning of an operating phase does not auto- matically turn off the semiconductor devices which were conducting during the previous phase and which have to be brought to the blocking state. This turn-off must be carried out autonomously. These two differences - the higher frequency of commutations and, espe- cially, the different mode of commutation -justify the first two chapters in this work: - Chapter 1 examines general notions concerning converters, supplies and loads, and more especially, how they can be characterized with regard to commutations.

A propos du livre

Présentation de l'éditeur

This book is the third in a series of four devoted to power electronic converters. The first and second of these books concern Ac to Dc conversion.This volume examines Dc to Dc conversion. The fourth is devoted to Dc to Ac conversion. Dc-Dc converters are probably the most widely used since their field of application extends from small power Switch- Mode Power Supplies to high power Choppers for traction ap- plications. Chapter 1examines general notions concerning converters, supplies and loads, and moreespecially, how they can be characterized with regard to commutations. Chap- ter 2 presents power semiconductor devices: diodes, thyri- stors (conventional and Gto), transistors (bipolar, Mos, Igbt,. . .) and associations. As commutations are an essential phenomenon in Dc-Dc converters, the transient behaviour of these devices is analyzed in detail. Chapter 3 gives a gene- ral presentation of chopper structures. Chapter 4 provides a quantitative analysis of the most common types of choppers with direct energy transfer. Chapter 5 examines the most commonly used procedures employed for turning off thyristors in choppers. The most widely used configurations of switch mode power supplies form the basis of the analysis in chap- ter 6. An appendix is devoted to snubbers. An important bi- bliopraphy is added. The aim of this collection written by university specialists working in close cooperation with in- dustry, is to present an up-to-date synthesis in the field of electrical engineering in rapid evolution and fast deve- lopment. Their guiding principle is to provide an useful and practical tool to power electronics specialists, whether they are designers or users of power converters, in activity or graduating.
