Core loss modeling part III

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

Stuck in a car

Alix Paultre, Editorial Director, PSD

Almost all of us have spent a large amount of their lives in a car. From being ferried from the hospital at both, to school as a child, or to work (and if you are lucky, vacation) as an adult. (You could say that the car made moot the riddle of the Sphinx.) People have been conceived, born, and died in cars si

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
