Figure 1: Gate driver circuit diagram with a Bourns transformer
While gate driver-based converters deliver improved efficiency, speed and signal integrity, their high frequency switching features can produce elevated levels of conducted electromagnetic interference (EMI), posing challenges to electromagnetic compatibility (EMC) and overall system reliability. To solve this

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 st

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, much of t

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 pr

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, dr

Figure 1. Authorities worldwide have adopted EPS energy-labeling protocols, and introduced stricter targets with each subsequent revision.
Energy Labeling Protocols for External Power Supplies Will Keep Getting Tougher and Reaching Further
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 and by se

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 un
