Impact of Voltage Sags on Electric-Vehicle Charger and Critical Voltage Sag Determination

IEEE Transactions on Power Delivery, 2016
This letter investigates the impact of voltage sags on electric-vehicle chargers and presents a method to determine the minimum symmetrical voltage sag during and after which chargers can both be kept stable. The proposed method is based on the constraints of pulse-width modulation (PWM), electric circuits, and small-signal stability.

Sensitivity of Programmable Logic Controllers to Voltage Sags

IEEE Transactions on Power Delivery, 2019
This paper discusses the sensitivity of programmable logic controllers (PLCs) to voltage sags based on mechanistic analysis and numerous tests. First, the sag sensitivity caused by different values of rated working voltage is shown through an analysis of

Voltage sags in industrial systems

Conference Record. Industrial and Commercial Power Systems Technical Conference 1991, 1993
A description is given of the causes of voltage sags in industrial plants, their impact on equipment operation, and possible solutions. The definition proposed focuses on system faults as the major cause of voltage sags. The sensitivity of different types of industrial equipment, including adjustable speed drive controls, programmable logic controllers,
