A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...

NOJA Power's OSM Automatic Circuit Reclosers are being successfully utilized as capacitor switches in Colombia. NOJA Power reclosers can be used in situations beyond the traditional protection grading ...

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

Although shunt capacitors offer several advantages at all voltage levels, those advantages come at a price. Not only must you purchase, install, and maintain capacitor equipment, you must be able to ...

How the fast switching speeds and other characteristics of SiC devices create new challenges in DC-link capacitor design. Key ...

High-voltage transient spikes generated during power conversion or gate-drive switching can be very harmful. In a motor-drive application, voltage derivation over time (dV/dt) transients may break the ...

We often run into the situation where there are two capacitors, one of them charged up to some voltage level and the other at some lower voltage level which, for purposes of this discussion, we will ...

I remember debugging a compact PLC power board used in a packaging line. The system worked perfectly on the bench. In the field, it started rebooting every few hours. No obvious faults. No overheating ...
