What is 2020 11th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC) - A Novel Controllable Bidirectional switching-capacitor based Buck-Boost Charger for EVs about?

This paper proposes a new on-board bidirectional switching-capacitor based buck-boost charger, which is capable to control active and reactive power in two modes (G2V and V2G). This on-board charger enables the EVs and PEVs to work as distributed generators (DGs), reactive power compensators, and voltage regulators. The proposed two-stage charger has the ability to work as buck-boost converter in both modes owing to its switching-capacitor base structure, which is the significant advantage of that. It has sinusoidal AC input current that its total harmonic distortion (THD) is low. A suitable control method is introduced, which can control the active and reactive power in both modes depending on smart grid commands or customer requirements. The simulation is done in MATLAB/SIMULINK software under grid voltage and results validate the system analysis. A laboratory prototype of the proposed charger is built and experimental results confirm simulation ones.
