Inrush Current Testing

2020 IEEE Applied Power Electronics Conference and Exposition (APEC), 2020
Inrush current testing is used for a variety of purposes including sizing fuses and carrying out power supply performance verification. Effective, accurate inrush testing can do more, including enabling power quality measurements and generating exemplars for machine-learning systems monitoring the power line.

An Ultra-Fast Inrush-Current-Free Startup Method for Grid-tie Inverter without Voltage Sensors

Applied Power Electronics Conference, 2023
This paper proposes an ultra-fast inrush-current-free startup method for grid-tie inverters without voltage sensors and phase-locked loop (PLL). Traditionally, the grid-tie inverter needs the voltage measured from points of common couplings (PCC) to ...
