Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

Adapted from The Circuit Designer's Companion, Third Ed., by Peter Wilson (Newnes). [Part 1 began a look at grounding: when to consider it, how chassis materials affect it, and the problem of ground ...

The transformation of the power landscape involves more than just generation. The distribution of electricity is being changed as well, with technology designed to make electrical systems safer, more ...

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: ...

Wide-bandgap (WBG) power semiconductors—and silicon-carbide (SiC) devices in particular—can help significantly improve the energy efficiency and reliability of various types of power converters. These ...
