Simply put, designing a power supply is a major undertaking. After making your build vs. buy decision, you face a myriad of circuit choices—more than you probably realize. Building a power supply used ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...

Designing flyback transformers for switch-mode power supplies involves many calculations. A spreadsheet can make short work of this otherwise-tedious task. When you develop flyback power supplies, ...

Common switch-mode power supply design errors and their appropriate rectification are discussed by Abe Ibraheim, Kenneth Armijo and Piyu Dhaker. Power transistors have a minimum and maximum duty cycle ...

The never-ending drive towards smaller and lighter products poses severe challenges for the power supply designer. In particular, disposing of excess hear generated by power semiconductors is becoming ...
