Power Electronics Handbook, Second Edition

Power electronics, which is a rapidly growing area in terms of research and applications, uses modern electronics technology to convert electric power from one form to another, such as ac-dc, dc-dc, dc-ac, and ac-ac with a variable output magnitude and frequency. Power electronics has many applications in our every day life such as air-conditioners, electric cars, sub-way trains, motor drives, renewable energy sources and power supplies for computers. This book covers all aspects of switching devices, converter circuit topologies, control techniques, analytical methods and some examples of their applications.

* 25% new content
* Reorganized and revised into 8 sections comprising 43 chapters
* Coverage of numerous applications, including uninterruptable power supplies and automotive electrical systems
* New content in power generation and distribution, including solar power, fuel cells, wind turbines, and flexible transmission

Pointwise Gridgen 16.0.R2

Pointwise, the next-generation of CFD meshing software, is now available. A new, modern, intuitive graphical interface, undo & redo, highly automated mesh assembly, and other features simplify mesh generation like nothing before.

What does Gridgen do?

* Gridgen generates structured hex, unstructured tet, and hybrid meshes...

* on CAD data imported from its native files and without repair...

* and exports meshes in the native formats of many CFD and other solvers...

* while running on Windows (Intel & AMD), Linux (Intel & AMD), Mac, and Unix.

What makes Gridgen special?

* The meshes it generates are of high quality leading to more accurate solutions and faster convergence.

* It's easier to learn, use, and remember how to use than other meshers and includes a scripting language so that you may customize the software for your purposes.

* Technical support is promptly provided by engineers with industry experience who understand how CFD can impact the design process.

VariCAD 2007 3.03

VariCAD is a 3D/2D CAD system for mechanical engineering. In addition to standard tools for 3D modeling and 2D drafting, the CAD system provides tools for sheet metal unbending and crash tests, libraries of standard mechanical parts (ANSI, DIN) and symbols, mechanical part calculations and tools for working with bills of materials (BOMs) and title blocks. VariCAD supports STEP, STL, IGES, DWG and DXF file formats.

The comprehensive CAD software enables designers to quickly create, evaluate, and modify their models. It is compact, fast, easy to use, and provides everything one needs for mechanical design. The CAD system is sold "fully loaded", including all features and functions, for one affordable price.
