Abstract |
This paper proposed a modular multilevel topology using power electronics transformersfor the modular drivetrain of electric vehicles (EV). Because of its high modularity, the topology canbe easily applied to a wide range of EVs, from personal vehicles to passenger cars. Compared withtwo conventional modular multilevel converters, fewer submodules are needed and its control is thussimpler. The topology can also balance voltage of batteries without an equalization circuit and has lowharmonics distortion. Moreover, according to the simulation results, the topology has higher overallefficiency than the conventional 6-switch 2-level inverter structure in synthesized driving cycles. |
