Cascaded Interleaved DC to DC Converter for Bidirectional Electric Vehicle Charging Station
摘要
The dc–dc bidirectional step-up interleaved converter, utilizing a cascaded topology with a central coupling capacitor, constitutes the core component of electric vehicle charging stations in their bidirectional form. Both charging and discharging of the EV batteries will thus efficiently be enabled and operational flexibility increased through this converter [1]. For a unified model that brings together all switching intervals under one model, this paper attempts to obtain an accurate analytical framework for the design of robust control strategies. Its reliability and efficiency were successfully validated through extensive stability analyses, simulations, and results from experiments [2]. Hence, this converter can support the future dynamic requirements for charging an electric vehicle by efficient power management and a growth rate in the electric vehicle charging networks.
