Novel EV drive train topology — A review of the current topologies and proposal for a model for improved drivability

The use of Direct Current to Direct Current (DC-DC) converters in Electric Vehicles (EV) drive trains allows for optimal combination of a power source complementing an energy source. Various topologies have been analysed and compared for their best features. A set of parameters has been created, based on which a new topology has been developed. The new topology is modular and allows for redundancy while improving driveability and has the potential to reduce cost of the drive train, by increasing the life expectancy of the energy sources.
