Book Description

When designing switch-mode power supplies (SMPSs), engineers need much more than simple "recipes" for analysis. Such plug-and-go instructions are not at all helpful for simulating larger and more complex circuits and systems. Offering more than merely a "cookbook," Practical Computer Analysis of Switch Mode Power Supplies provides a thorough understanding of the essential requirements for analyzing SMPS performance characteristics. It demonstrates the power of the circuit averaging technique when used with powerful computer circuit simulation programs.

The book begins with SMPS fundamentals and the basics of circuit averaging models, reviewing most basic topologies and explaining all of their various modes of operation and control. The author then discusses the general analysis requirements of power supplies and how to develop the general types of SMPS models, demonstrating the use of SPICE for analysis. He examines the basic first-order analyses generally associated with SMPS performance along with more practical and detailed methods for developing SMPS and component models. The final chapter features the circuit-averaging macromodel of the integrated circuit PWM controller illustrated through analyses of three power supplies.

Practical Computer Analysis of Switch Mode Power Supplies builds a strong foundation on the principles of SMPS analysis, enabling further development and advancement of the techniques while supplying meaningful insight into the process.
