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 ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

This Design Idea is able to turn off inductive loads at a very fast rate. When connected to a load (here 15mH + 10?), the modified freewheeling path in the clamping circuit based around M2 reduces the ...

Imagine a future where your electric car is seamlessly and wirelessly charged by the highway that it rides on, no plug required. That's what Technologies is working on today and what it is ...

Mechanical relays, contactors, and switches control the flow of electricity by the mechanical action of two conducting elements. The physical contact of two conducting elements creates a path for ...

Tesla Cybertruck is ready for wireless inductive charging based on new connectors found on the electric pickup truck’s battery pack. The automaker never seemed interested in wireless charging for its ...

Though MOVs are relatively simple devices, choosing the right one requires some knowledge. Varistors, also called metal-oxide varistors (MOVs), are used to protect sensitive circuits from a variety of ...

Electric clutches and brakes sometimes fail for lack of proper electrical-suppression circuitry. But it’s not difficult to design a suppressor • Electric brakes and clutches operated directly from ...

So you have power circuit breakers at your facility, and they seem to be just fine, sitting there quietly doing their job. What you may not realize is that even though your circuit breakers are ...

For whatever reason, cell phone companies really don’t seem to care about giving you a good battery for your phone. Here’s a great hack if you happen to have a purse — turn it into an inductive ...
