Figure 1: Contact wear in an electromechanical relay

As a mature technology, electromechanical relays and circuit breakers are well established, however they continue to suffer from some inherent weaknesses. Moving to solid-state technology can address these but introduces its own challenges. So, what is the right solution? In the movies, whenever the

Power Supplies for Railway Applications â€

Figure 1. The range of railway applications is very wide

In a study presented at the international rail exhibition, Innotrans 2016 in Berlin, the European Rail Industry summarized the state of the business as representing a market size estimated to reach 185 billion Euro by 2020. Of course, the power supplies share of that amount is marginal compared to heavy rolling

Horticulture Lighting Drives Plant Growth

Figure 1. Horticulture Facility

The market for light-emitting diodes (LEDs) has been experiencing continuous growth for several years. The reasons for this include, for instance, the low costs of the LEDs, whose energy efficiency and capabilities, brightness, and color scheme can be adapted individually to the respective requirements. In addition,

The Future of MicroLED Displays Using Next-Generation Technologies

Figure 1. Brightness in Daylight

MicroLEDs (micro-light-emitting diodes) are an emerging display technology that, as the name implies, use very small LEDs for pixels. Much the same as any other current display technology, it combines red, green and blue sub-pixels to reproduce a colour. Although there are currently no microLED displays in mass

Smart yet Frugal: Energy-Saving, Next-Generation Lighting

Figure 1. The FL7740 and FL7760 are a complete dimmable solution for modern LED lighting

Lighting is important to us – a fact borne out by an estimate from the US Energy Information Administration that we use the same amount of energy to light our homes (129 Billion kWh – 9% of total consumption) as the total amount we use to wash and dry our clothes, use our computers and cook. However,

Single 2MHz Buck-Boost Controller Drives Entire  LED Headlight Cluster, Meets CISPR 25 Class 5 EMI

Figure 1. LT8391A 2MHz 16V, 1.5A automotive buck-boost LED driver passes CISPR 25 Class 5 EMI

Automobile LED headlight clusters combine high and low beams, daytime running lights, and sometimes signal and clearance lights into a single headlight cluster. The components of the cluster can have vastly different driver requirements, including voltage and current requirements, topologies, power levels or

Energy Labeling Protocols for External Power Supplies Will Keep Getting Tougher and Reaching Further

Figure 1. Authorities worldwide have adopted EPS energy-labeling protocols, and introduced stricter targets with each subsequent revision.

Recent delays in the introduction of mandatory energy-performance standards should not be interpreted as a slackening in the pace of regulatory change. Energy-performance standards for high-tech products can become more effective in helping protect the planet by being more broadly adopted worldwide
