Efficiency, impedance, and power quality are key parameters to measure in data-center power-distribution networks. In part 1 of this series, we looked at the evolution of data-center power architectures in the age of artificial intelligence (AI). Here, we’ll look at some key power parameters and the test instruments needed to measure them. Q: What are […] The post AI data center power…

The EPC7050PCSH, EPC7066PCSH and EPC7065PCSH support 15 V, 25 V and 40 V ratings respectively, each with 101 A continuous current capability, backside thermal pads, zero reverse-recovery charge and radiation ratings of TID > […] The post eGaN transistors…
Power-distribution architectures are evolving to meet the energy needs of artificial-intelligence workloads. Data-center power consumption regularly makes headlines, with consumers fearing that data-center operators are driving up electricity prices. The IEA expects that power demands will continue to rise as data centers increasingly run demanding artificial-intelligence (AI) workloads. The…
Temperature sensors in electric vehicle (EV) battery packs measure temperature only where they are mounted. Nevertheless, a battery management system (BMS) must use limited local readings to reconstruct the pack temperature field, detect developing hot spots, and drive cooling decisions that reflect cell-level conditions. This article reviews how sensor placement and density affect BMS monitoring…
Antaira Technologies has announced the availability of the LSP Series, a line of IP30-rated multi-port Power-over-Ethernet (PoE) surge protection devices for industrial networks. The dual-port LSP-0200X-bt-100-T and four-port LSP-0400X-bt-100-T support 100W 802.3bt PoE++ pass-through per data line, data speeds from 10/100M to 10GbE and operation from -40°F to 167°F (-40°C to 75°C). The DIN-rail or…
In my electronics lab, I am plagued with some odd high-frequency interference. When I’m looking at low-level signals with my scope set to 10, 20, or 50 mV/division, I can see repetitive waveforms with ~100 kHz and ~7 MHz content. This is especially insidious: It’s even present between adjacent earth ground connections. To track noise […] The post Tracking down sources of EMI/RFI appeared first on…
By Alexsander Tamari, Technical Marketing Engineer, Altium Hardware design teams often treat the printed circuit board component library as a drawing repository, a collection of schematic symbols and 2D footprints required to pass a design rule check and generate Gerber files. But viewing a component library strictly through the lens of ECAD is a fundamental […] The post Beyond Symbols and…
