作者：Zhijun Wang; Xiaoqiang Guo; Jian Li; Xiaoyu Wang

摘要：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.
