SMPS Tutorial (1): Introduction - Switched Mode Power Supplies and Power Conversion

In portable systems, a number of low-voltage, low-power DC voltage supplies are needed. To provide these from a single battery source, some form of voltage conversion is necessary.

Switching Power Supply Design, 3rd Ed

A switched-mode power supply switching-mode power supply , switch-mode power supply , switched power supply , SMPS , or switcher is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source often mains power to DC loads, such as a personal computer , while converting voltage and current characteristics. Unlike a linear power supply , the pass transistor of a switching-mode supply continually switches between low- dissipation , full-on and full-off states, and spends very little time in the high dissipation transitions, which minimizes wasted energy. A hypothetical ideal switched-mode power supply dissipates no power. Voltage regulation is achieved by varying the ratio of on-to-off time also known as duty cycles.

Sponsored by Texas Instruments Congratulations to our winners! The book starts out with power supply basics such as voltage regulation and power component selection, and then addresses advanced topics such as magnetics design, minimizing EMI, and topology selection. The book is a readable resource that contains equations and theories but also chronicles the history of the power supply industry. Actual measurements are also used throughout to illustrate practical example circuits. This book will be your key reference guide whether you are a new or seasoned power engineer.

Paul Pickering Aug 15, Download this article in PDF format. Back when Yoda was a Jedi-in-training, designing a power supply was relatively straightforward. We lived in a linear world: The front end of a typical power supply consisted of a transformer feeding a full-wave bridge rectifier followed by a large-value filter capacitor. Incidentally, since Yoda was over years old when this picture was taken Fig. But we digress. Master many skills you must.
