Thermoelectric generators are getting more R&D attention
Thermoelectric generators may lack the visible appeal of solar panels, but their demonstrated usefulness is spurring more research into lower-cost fabrication techniques.
A potential firmware mistake may lead to control instability
The control delay in digital power supply implementation will reduce phase margin and cause oscillation, calling for a robust control scheme.
Don’t ignore the need for small, low-capacity batteries
A low-cost printed battery offers one-time use after water activation and has minimal post-use environmental impact.
Two simple isolated power options for 8W or less
Here are two approaches that both reduce design complexity and noise coupling in isolated bias power supplies.
Onboard fixtures for fault testing
Running through circuits that can be employed to test your PCB's overvoltage, undervoltage and incorrect sequencing detection capabilities.
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.
