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: 48 V server architecture in a typical data center
Introduction
Approximately half of the energy consumed in a typical data center is wasted, either during power conversion or through cooling. Given the increasingly urgent requirement to reduce CO2 emissions, this undesirable situation required addressing at both system and converter levels. Research [1] indicates that using 48 V power distribution at the rack level would help to reduce power los

Figure 1: IoT-enabled sensor technology is set to revolutionise waste management
Waste collection is an essential service that municipal bodies need to perform on a regular basis. EU figures (published in 2020) show that each citizen resident in one of its member states on average generated 505kg of garbage waste each year. When applied to the entire population, that clearly constitutes a
