Switching Power Supplies A - Z

Front Cover
Elsevier, May 10, 2012 - Technology & Engineering - 768 pages

Switching Power Supplies A - Z is the most comprehensive study available of the theoretical and practical aspects of controlling and measuring Electromagnetic Interference in switching power supplies, including input filter instability considerations.

The new edition is thoroughly revised with six completely new chapters, while the existing EMI chapters are expanded to include many more step-by-step numerical examples and key derivations and EMI mitigation techniques. New topics cover the length and breadth of modern switching power conversion techniques, lucidly explained in simple but thorough terms, now with uniquely detailed "wall-reference charts" providing easy access to even complex topics.

  • Step-by-step and iterative approach for calculating high-frequency losses in forward converter transformers, including Proximity losses based on Dowell's equations
  • Thorough, yet uniquely simple design flow-chart for building DC-DC converters and their magnetic components under typical wide-input supply conditions
  • Step-by-step, solved examples for stabilizing control loops of all three major topologies, using either transconductance or conventional operational amplifiers, and either current-mode or voltage-mode control

About the author (2012)

Sanjaya Maniktala is the author of several power electronics books and currently CTO of his own company, Chargedge. Mr. Maniktala earned several patents in power conversion and power over ethernet, including the floating buck regulator topology and mode transitioning in a buck-boost converter using a constant duty cycle difference technique. He initiated the first unified approach to switching topologies and was also the first to recognize, articulate and apply fundamental power and frequency scaling principles to resonant topologies, which resulted in the world's simplest one-page design methodology for LLC converters. Sanjaya holds degrees in physics from St. Stephen's College Delhi, IIT Bombay and Northwestern University Illinois. Professionally, he has worked in well-known companies such as Freescale, Siemens AG and Broadcom and spent over five years at National Semiconductor (now Texas Instruments) in Santa Clara, California.
