Based on the voltage-following strategy (VFS), the EVFS is proposed to reduce the switching counts, whereas the switching losses can be reduced. Through simulation and experimental analysis, it can be observed that the EVFS achieves a substantial reduction in switching counts. Finally, both simulation and experimental results verify the performance and feasibility of the proposed EVFS.Electronic load | switching loss | zero-sequence current[SDGs]SDG7Enhanced Voltage-Following Strategy to Reduce Switching Loss for Programmable Electronic Loads With Shared DC Busconference paper10.1109/IFEEC58486.2023.104584952-s2.0-85189749912https://api.elsevier.com/content/abstract/scopus_id/85189749912
