Since the mid-1980s, semiconductor technology has promised to provide smart power products for solid-state relays that could carry high current and provide unique functions for customers. However, ...

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 ...

Hybrid relays are changing the way we think about switching inside electronic circuits. By combining the fast response of solid-state components with the reliability of mechanical contacts, these ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

DARPA selected RTX Corporation, Draper, and BEAM Co to design prototype lop wireless optical power relays. The Persistent Optical Wireless Energy Relay (POWER) program, aimed at revolutionizing energy ...

Potential relays are commonly found on many smaller, single-phase, capacitor-start, capacitor-run motors in the HVACR industry. Their function is to assist in starting the electric motor. Potential ...

There are several factors in taking a particular design approach, and they are not always independent. Some of the considerations when designing drivers for inductive loads are size, cost, switching ...

Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...

Love it or hate it, wiring is a part of any project car. You may loathe the idea of installing relays, but without them, wiring would be much more difficult. HOT ROD ...
