The design of a switching power supply has always been considered a blend of magic and art by every engineer that designs one for the first time. Fortunately, today the market offers different tools ...

Power-supply designers frequently encounter projects where the input voltages are much higher compared to the low output voltages usually require to power the target equipment. Typical output needs ...

Prior knowledge needed: ECEA 5700 Introduction to Power Electronics, ECEA 5701 Converter Circuits, ECEA 5702 Converter Control, ECEA 5703 Magnetics Design, ECEA 5705 Averaged Switch Modeling and ...

In Power Tip #3, we discussed how the source impedance of an input filter can turn resistive, and how it can interact with the negative input impedance of a switching regulator. At worst case, these ...

Noise is a constant problem in power-supply design. While there are FCC limits on the electromagnetic interference (EMI) radiating out into the air as well as the conducted noise that your design ...
