Bidirectional DC-DC Resonant Converter Design for Electric Vehicle Charging Stations Integration to MVDC Grids

The extensive use of electric vehicles (EVs) needs ultra-fast-charging stations with high charging power greater than 22 kW (PCharging >22kW). Medium voltage direct current (MVDC) grids can provide the best solution for the high demand of EVs and fast-charging stations infrastructures with the existing distribution grids. The resonant bidirectional dual active bridge (DAB) DC-DC converter can be a promising technology in integrating an electric vehicle charging station (EVCS) with MVDC grid. This work focuses on the converter design with voltage control and stability by applying two different control strategies mainly: PI control and sliding mode control (SMC). All simulations will be performed in order to present the feasibility of the proposed solution and compare the results of each control methods. This comparison, for the first time, in the medium voltage level can open new insights for using nonlinear control methods such as SMC to ensure stability and obtain better dynamic performance
