DESIGN OF A BIDIRECTIONAL DC-DCCONVERTER FOR HYBRID ELECTRICVEHICLES (HEV) USING MATLAB

[摘要] The design of a 60 kW bidirectional DC-DC converter is addressed in this paper. The paper also discusses the operation and role of dc-dc converter in Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV). Various circuits and their analysis are done to review the operation and design of converter. Results show that at 20Hz operation converter efficiency is better when ETD49 shape is used rather than EC70. However efficiencies are greater with ferrite materials rather than iron powder.
