Bidirectional DC-DC converter, electric vehicle, power electronic interface, multilevel converter, high voltage.
The paper presents a soft switched isolated multilevel DC-DC converter topology to interface the high voltage battery pack and traction inverter in electric vehicles. The converter has bidirectional power flow capability and high DC voltage gain. Detailed analysis of the converter and simulation results along with preliminary hardware results are presented.
