[010] The Nine Most Useful Power Topologies
For most power supply applications, a handful of topologies continue to be used after more than 30 years. Simplicity and ruggedness keep these circuits relevant today.
[009] Is your Input Filter Causing Trouble?
You can analyze your power supply filter quickly and easily with free downloadable software. This allows you to check for filter impedance interactions, attenuation, and proper damping.
[008] Why Do Power Supplies Fail?
Switching power supplies remain a weak link of most electronic systems and fail more often than they should. The reasons for failure are discussed.
[007] Capacitors for Switching Power Supplies
The changing characteristics of the capacitors used in power supplies are examined. They are not as simple as most engineers assume.
[006] The Digital Power Supply Revolution
Digital power is all the rage now, but don't expect it to shorten your design time, or to eliminate the need for complete optimization of the analog parts of the power supply.
[005] High Frequency Power Inductor Design
Proximity Loss in Magnetics Windings
[004] HF Transformer Measurement and Modeling
How to measure and model high-frequency magnetics for switching power supplies. Essential steps for both custom-designed parts, or purchased components.
[003] Gate Drive Design Tips
Simple and effective gate drive schemes are presented, with some warnings about things that can go wrong.
[002] Sepic Converter Analysis
The Sepic converter dc analysis is presented, showing why this is a popular converter. Beware of the ac characteristics though.
[001] Complexities of Switching Power Design
Even the simple buck converter can present very complex and changeable control characteristics when interacting with surrounding components and operating in different modes.
