Advanced DC/DC Converters by Fang Lin Luo, Hong Ye

By Fang Lin Luo, Hong Ye

DC/DC conversion ideas have passed through fast improvement in contemporary a long time. With the pioneering paintings of authors Fang Lin Luo and Hong Ye, DC/DC converters have now been looked after into their six generations, and through a coarse count number, over 500 diverse topologies presently exist, with extra being constructed every one year.

Advanced DC/DC Converters bargains a concise, sensible presentation of DC/DC converters, summarizing the spectrum of conversion applied sciences and providing many new principles and greater than a hundred new topologies. The remedy starts with history fabric on DC/DC conversion and discussions on voltage raise and super-lift converters. It then proceeds via each one new release, together with the groundbreaking 6th generation--converters built by way of the authors that may be cascaded for prime voltage move achieve.

More than 320 figures, 60 tables, and 500 formulae let you extra simply seize the final constitution of complicated DC/DC converters, supply quickly entry to specific facts, and assist you fast make certain the values of your individual circuit parts. Nowhere else within the literature are DC/DC converters so logically taken care of and systematically brought. Nowhere else are you able to locate particular info on prototype topologies that signify an immense contribution to fashionable strength engineering.

Circuit Design and Simulation with VHDL (2nd Edition)

This textual content bargains a entire remedy of VHDL and its functions to the layout and simulation of actual, industry-standard circuits. It specializes in using VHDL instead of exclusively at the language, exhibiting why and the way specific sorts of circuits are inferred from the language constructs and the way any of the 4 simulation different types could be applied. It makes a rigorous contrast among VHDL for synthesis and VHDL for simulation. The VHDL codes in all layout examples are whole, and circuit diagrams, actual synthesis in FPGAs, simulation effects, and explanatory reviews are integrated with the designs. The textual content stories primary ideas of electronic electronics and layout and incorporates a sequence of appendixes that provide tutorials on vital layout instruments together with ISE, Quartus II, and ModelSim, in addition to descriptions of programmable common sense units during which the designs are carried out, the DE2 improvement board, ordinary VHDL programs, and different beneficial properties.

All 4 VHDL variations (1987, 1993, 2002, and 2008) are lined. This multiplied moment variation is the 1st textbook on VHDL to incorporate an in depth research of circuit simulation with VHDL testbenches in all 4 different types (nonautomated, totally computerized, sensible, and timing simulations), followed through whole sensible examples. Chapters 1--9 were up-to-date, with new layout examples and new information on such issues as facts kinds and code statements. bankruptcy 10 is solely new and offers solely with simulation. Chapters 11--17 also are solely new, featuring prolonged and complex designs with theoretical and useful assurance of serial information communications circuits, video circuits, and different themes. there are various extra illustrations, and the workouts were up-to-date and their quantity greater than doubled.

Fundamentals of Liquid Crystal Devices

From computing device desktops and cell phones to electronic cinema, Liquid Crystal screens (LCDs) are crucial parts in an expanding array of hugely fascinating buyer electronics and conversation units, and are already the essential expertise utilized in flat panel monitors. This inter-disciplinary booklet is meant as an introductory consultant to the basic houses of liquid crystals and their purposes in exhibit and photonic units, delivering a simple knowing of the physics, optics, electro-optics, and fabric facets for cutting-edge show and photonic units.

They can be employed in multiple-lift switched capacitor converters. 20. Since there is no inductor in the pump, it is applied in © 2003 by CRC Press LLC L i1 . 17 ZETA pump. switched-capacitor converters. The main switch S and diode D1 are synchronously on and off, but the slave switch S1 and diode D2 are alternately off and on. Usually, the positive push-pull pump works in push-pull state continuous operation mode. 21. Since there is no inductor in the pump, it is often used in switched-capacitor converters.

Main power losses are produced during the switch-on and switch-off period. How to reduce the power losses across the switch is the clue to increasing the power transfer efficiency. Soft-switching technique successfully solved this problem. Professor Fred Lee is the pioneer of the soft-switching technique. He established a research center and manufacturing base to realize the zero-current-switching (ZCS) and zero-voltage-switching (ZVS) DC/DC converters. His first paper introduced his research in 1984.

4 Voltage Lift Converters Voltage lift technique is a good method to lift the output voltage, and is widely applied in electronic circuit design. After long-term industrial application and research this method has been successfully used in DC/DC conversion technique. Using this method the output voltage can be easily lifted by tens to hundreds of times. Voltage lift converters can be classed into selflift, re-lift, triple-lift, quadruple-lift, and high-stage lift converters. The main contributors in this area are Dr.
