Powering electronic devices requires the testing of power supply and charging circuits, battery management systems (BMSs), and battery cells. Many of these circuits require voltage, current, and power measurements, plus numerous others. Oscilloscopes and probes let you see the waveforms in power-delivery circuits, but the circuits themselves may need simulated batteries and simulated loads. That’s […]

APEC 2024: Test equipment
Test equipment is everywhere. Every trade show has it regardless of the focus. Power is no exception. At APEC 2024, EE World visited several booths displaying test equipment: meters, oscilloscopes, source-measure units (SMUs), bench power supplies, and electronic loads. The photos and videos below highlight what we saw, presented in alphabetical order by company. In […]
Portable power quality analyzer decodes three-phase power problems
The Hioki PQ3198 Power Quality Analyzer can be used for assessing power usage as well as for investigating power supply problems such as voltage drops, flicker, harmonics, and other electrical issues. Hioki portable power analyzers can measure single to three-phase lines with a high degree of precision and accuracy. New features include the ability to […]
