An Overview of Current-Fed Power Processing

A technical paper on Magna-Power Electronics signature current-fed power processing topology with a comparison to alternative approaches to high-power switch-mode power supply design.

Control Loop Modulation Applied to Programmable DC Power Supplies

Modulation allows a set point adjustment of voltage or current by another input. Modulation signals can be derived from an external device, such as a thermistor, or from sampling output current or voltage.

Getting the Best Performance from AC to DC Power Supplies in Abusive Environments

Five frequently seen power supply integration problems that may affect the product's lifespan and measures for correcting them, including: power supply grounding, line voltage, switching remote sense leads, over current trip fault, and operating environment.

Peak-to-Peak Output Voltage Measurements of Switching Power Supplies

The peak-to-peak output voltage measurement requires a setup that is difficult for customers to replicate. This article explores the methods and physical apparatuses used by Magna-Power to measure peak-to-peak output voltage ripple.
