Electric Bus Charging Pile Design and Simulation Based on MMC

Direct connection between electric vehicle, AC and DC microgrids, or other DC source/load and Modular Multilevel Converter (MMC) will affect the safe operation of MMC, increase control difficulty. Basing on MMC and Isolated Bidirectional full-bridge DC-DC Converter (IBDC), this paper presents a new topology for electric bus charging and builds the simulation of the new electric bus charging topology with the aid of Pscad simulation tools, then, analyzes the simulation results., which can make use of energy more efficiently, save charging cost, and effectively reduce the impact on the power network when electric bus is charging.
