Take the "black magic" out of switching power supplies with Practical Switching Power Supply Design! This is a comprehensive "hands-on" guide to the theory behind, and design of, PWM and resonant switching supplies. You'll find information on switching supply operation and selecting an appropriate topology for your application. There's extensive coverage of buck, boost, flyback, push-pull, half bridge, and full bridge regulator circuits. Special attention is given to semiconductors used in switching supplies. RFI/EMI reduction, grounding, testing, and safety standards are also detailed. Numerous design examples and equations are given and discussed. Even if your primary expertise is in logic or microprocessor engineering, you'll be able to design a power supply that's right for your application with this essential guide and reference!
Key Features
* Gives special attention to resonant switching power supplies, a state-of-the-art trend in switching power supply design
* Approaches switching power supplies in an organized way beginning with the advantages of switching supplies and thier basic operating principles

The BeOS is the exciting new operating system designed natively for the Internet and digital media. Programmers are drawn to the BeOS by its many state-of-the-art features, including pervasive multithreading, a symmetric multiprocessing architecture, and an integrated multithreaded graphics system. The Be engineering team also built in many UNIX-like capabilities as part of a POSIX toolkit. Best of all, the BeOS runs on a variety of Intel architectures and PowerPC platforms and uses off-the-shelf hardware.

This book explores the BeOS from a POSIX programmer's point of view, providing a comprehensive and practical guide to porting UNIX and other POSIX-based software to the BeOS. BeOS: Porting UNIX Applications will help you move your favorite UNIX software to an environment designed from the ground up for high-performance applications.
* Supports BeOS Release 3
* Provides a step-by-step guide to the porting process from downloading the source code to installing the application
* Explains how to port off-the-shelf utilities like Emacs and Perl as well as your own programs and tools to the BeOS
* Offers a comprehensive POSIX reference for anyone who is porting or writing software for the BeOS
* Furnishes a simple catalog of tools and features available on the BeOS
