Defeating the Challenges of Electromechanical and Solid-State Relays

Kevin Kilbane
Senior Product Manager, Silicon Labs

Electromagnetic relays (EMRs) are broadly used in motor control, automotive, HVAC, valve control, solar inverter and many other industrial applications. Over the last 10 years, solid-state relays (SSRs) have seen fast growth as they begin to replace EMRs. Designers have found that SSRs can address most of the limitations of EMRs. But as is often the case with alternative solutions, SSRs have their own set of tradeoffs that can challenge designers. A third alternative exists: using custom SSRs. Let's exam the limitations and tradeoffs of each approach.

Building Blocks for GaN Power Switches

A team of engineers from Cornell University, the University of Notre Dame and the semiconductor company IQE plc has created gallium-nitride (GaN) power diodes capable of serving as the building blocks for future GaN power switches — with applications spanning nearly all electronics products and electricity distribution infrastructures. Along with having many desirable features as a material, GaN is notorious for its defects and reliability issues. So the team zeroed in on devices based on GaN with record-low defect concentrations to probe GaN's ultimate performance limits for power electronics. They describe their results in a paper in the journal Applied Physics Letters.
