Accurately predicting core losses in magnetic components is difficult, and no less challenging in composite inductors. Several core loss models are available, all of which have their merits. This ...

For the PDF version of this article, click here. A switch-mode power supply incurs loss in many areas of its circuitry, including the MOSFETs, input and output capacitors, quiescent controller current ...

Electrical ratings are interdependent. The current through a component depends on the applied voltage (waveform and duty cycle) and the component impedance. The impedance of a component depends on the ...

Excessive use of electricity and poor efficiencies are no longer acceptable. Eliminating poor power factor will result in increasing electrical efficiencies and will reduce the overall use of ...
