The power supply voltage requirements in smartphones and tablets are growing due to a constant increase in functionality. And that is leading to a rise in the number of inductors in power supply ...

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 ...

Here’s a step-by-step design of a resonant-coupled inductor employed in a PFC EMI filter that doesn’t impact power factor. Over the past 40 years many of my designs included Power Factor Correction ...

As Lenz’s Law states, an inductor in a circuit opposes the flow of current through it because the flow induces an electromotive force (emf) that opposes it. In order to keep the current flowing ...

TT Electronics has introduced a range of coupled inductors with high temperature rating and AECQ200 certification for use in automotive power converter applications. The HA78D series shielded SMD ...

Active inductors have emerged as a transformative component in CMOS radio frequency (RF) circuit design, effectively replacing traditional passive inductors with active semiconductor networks. By ...

As the process technology advances, the number of the transistors on an LSI chip has been increasing and their high speed operations generate more power supply noise while the low supply voltage ...

This course introduces the basic concepts of switched-mode converter circuits for controlling and converting electrical power with high efficiency. Principles of converter circuit analysis are ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

For RF inductor selection, José Martos and Heinz Zenkner stress the importance of evaluating inductance, natural resonant frequency, quality, DC resistance and rated current for high-frequency ...
