Figure 1: Comparison between conventional and PT-symmetry-based wireless power transfer schemes as the source–receiver resonant coupling rate κ varies as a function of transfer distance d. Figure 3: ...

After a four-part introduction, the LLC gain equation is finally introduced. This portion was delayed due to the need to explain that the LLC is a switched mode power supply (SMPS), yet the gain has ...

Because of the shell arrangements of electrons in various atoms and molecules, some substances are quite good at allowing a few electrons to move about freely (e.g., copper, silver, gold, aluminum), ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

One of the biggest contributors to power loss in power conversion circuits (DC-DC, AC-DC) are resistive losses when the semiconductor switches are in the ON stage. In order to create industry-leading ...
