Class 4 power: Coming soon to tech near you
Class 4 power releases engineers from old power limitations, enabling new power architectures for data centers, mobile networks, and other power-hungry technologies.
Teardown: Wireless charger with a magnetic personality
Take a conventional Qi charger. Beef up its output (for compatible to-be-charged devices, at least). Add magnets. Now buy it and tear it apart. That, in a nutshell, is today's editorial piece.
Understanding test challenges for emerging battery management systems
This article focuses on the current and future trends around BMS devices for automotive, and some key test challenges the industry is working to address.
Key considerations in powering an ADC
Knowing more about powering an ADC can improve data collection outcomes and avoid noise problems.
Forget Tesla coils and check out Marx generators
Building a Marx generator is easier than doing the popular the Tesla coil, since it doesn't require windings or as many high-voltage components.
Sneaky feedback paths that de-stabilize an otherwise stable feedback loop
Loop gain and loop phase tests should always be run at varying levels of excitation to see if the test results match each other at every excitation level.
Homebrew loop gain test transformer
Testing the loop gain and phase properties of the feedback loop in a power supply with a coax-on-toroid “homebrew” transformer.
Five major trends in power supply design for servers
A review of server power supply unit (PSU) design outlines future trends in power density, efficiency, control, and thermal performance.
Power designers face challenges with the rise of 5G
Power is one of the key challenges for 5G.
