Dr. Ray Ridley, Ridley Engineering

The first two parts of this article showed how the core losses for real waveforms could be modeled better. In the first part, a continuous expression was used to model a wide range of excitations. In the second part, the effect of duty cycle on the loss of the core material was included in a single equation. In

Electrolytic capacitor lifetime in power supplies

Gary Bocock, Technical Director, XP Power

Electrolytic capacitors are an essential ingredient in AC/DC power supplies, providing high Capacitance x Voltage (CV) and low Equivalent Series Resistance (ESR) in low-volume packages that simply cannot be achieved cost-effectively using alternative parts. With power density demands increasing and as the only com

LED Back Lighting Dominates Automotive Displays

Tony Armstrong, Linear Technology

Some of the key applications which drove the explosive growth of LEDs used to backlight thin film transistor (TFT) liquid-crystal displays (LCDs) included high definition (HD) TVs, portable tablet PCs, automotive infotainment displays and the myriad of handheld communication devices. However, in order to maintain th

Meeting PC Power Titanium specifications at light load

Zhihong Yu, Monolithic Power Systems

For AC/DC power supplies, there is by nature phase differences and distortion between input currents and voltages due to the existence of holding capacitors and various load features. Here, only the instantaneous product of current and voltage produces power that can actually be used by the appliance, and the pow

Assessing next-generation discretes Part II*

Dr. Thomas Barbieri, Wolfspeed, A Cree Company

In Part 1 of this discussion, we explored the functionality of a series-connected avalanche transistor pulser, specifically for the purpose of evaluating dV/dt ruggedness of SiC Schottky diodes. In this issue, the diodes are tested with the new pulser design. SiC Schottky diode dV/dt ruggedness testing With a
