Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding interconnections, and increasing dependence on distributed energy ...

The addition of a components and an unused NC contact to a dc supply provides a power-reducing feature to a relay driver circuit. Electromagnetic relays need much less power for holding than they do ...

Here’s a MEMS relay with an integrated FET that can handle higher power levels, breaking away from the “low power” moniker associated with MEMS parts. Paul Rako takes a closer look at what makes this ...

Relays are often used as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. On the other hand, the power dissipation in a ...

The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...
