Power Electronic Converters DC-DC Conversion
Free Download Power Electronic Converters: DC-DC Conversion by Robert Bausière , Francis Labrique , Guy Séguier
English | PDF | 1993 | 422 Pages | ISBN : 3642524567 | 27.3 MB
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.

Power Electronic Converters DC-AC Conversion
Free Download Power Electronic Converters: DC-AC Conversion by Guy Séguier , Francis Labrique
English | PDF | 1993 | 460 Pages | ISBN : 3642503241 | 25 MB
This is the final volume in a four-volume series concerning POWER ELEC TRONIC CONVERTERS. The first volume studies AC/DC conversion, the second studies AC/ AC conversion, and the third DC/DC conversion. This final volume deals with DC/AC conversion, i.e. with inverters. At the output of an inverter fed by a DC voltage supply, this voltage is alternatively found with one polarity and then with the other; in other words, an AC voltage made up of square pulses is obtained. Filtering must be carried out if, as is normally the case, a virtually sinusoidal voltage is required: this problem of filtering underlies the entire study of inverters. In some applications, the load itself provides the filtering. In others, a filter is installed between the inverter and the load; however, as it will be shown in Chap. 2, in cases where the filtered voltage is at industrial network frequency and comprises only a single square-wave pulse per half-cycle, the filter becomes bulky and costly, and the results obtained are poor. Filtering problems explain the considerable development of inverters during the last years: - Firstly there is increasing use of pulse width modulation: each half-cycle is cut up into several pulses of suitable widths; this greatly simplifies filtering. The use of a chopping frequency which is much greater than the frequency of the fundamental components of the inverter output voltage and current has only been made possible by progress in the field of semiconductor devices.

Plastics for Electronics
Free Download Plastics for Electronics by Martin Goosey (Chief Scientist and Technology Fellow)
English | PDF | 1999 | 409 Pages | ISBN : 0412725606 | 38.8 MB
Polymeric materials are widely used during nearly all stages of the manufacturing process of electronics products and this book is intended to give an introductory overview of the chemistry, properties and uses of some of the more important classes of materials likely to be encountered in these applications. It is intended to serve primarily as an introduction to the use of polymers and plastics in the processing and manufacture of electronic and electrical components and assemblies. With no in-depth knowledge of polymers assumed, the book is ideal for engineers and researchers working in areas where electronics and polymer technology overlap. There are also numerous references for those wishing to delve deeper.

Piezoelectric Sensorics Force Strain Pressure Acceleration and Acoustic Emission Sensors Materials and Amplifiers
Free Download Piezoelectric Sensorics: Force Strain Pressure Acceleration and Acoustic Emission Sensors Materials and Amplifiers by Gustav Gautschi
English | PDF(True) | 2002 | 271 Pages | ISBN : 3540422595 | 24.3 MB
Sensors are the key to life and survival - and to the success of modern technology. Nature has provided living creatures with a wealth of sensors for a variety of measurands, such as light, sound, temperature, speed, motion, distance, force, pressure, acceleration, odor and so on - sensors, whose performance and specifications have often not been matched yet by man-made devices. Even at today's high level of electronics and information technology, sensors remain the crucial and decisive interface needed to reliably relate phenomena occurring in the environment to corresponding electric signals that can be processed to obtain the desired information and subsequent correct reaction of systems. Although the literature on sensors is extremely vast, there is one type of sensors which so far has received little attention: the piezoelectric sensor. Certainly, most handbooks on measurement mention briefly this type of sensor yet there is not a single book in the English language dedicated entirelyto piezoelectric sensors and giving a reasonably complete overview. There are only the books by [Gohlke 1955 and 1959] and [Tichy and Gautschi 1980], all in German.
