Item A Non-Isolated Buck-Boost DC-DC Converter for On-Board Electric Vehicle Powertrain(Institute of Electrical and Electronics Engineers Inc., 2023) Vinusha, B.; Kalpana, R.; Kishan, D.In this paper, a non-isolated buck-boost DC-DC converter for on-board electric vehicle powertrain is proposed. It has a universal-input voltage capability for the requirement of power factor correction in electric vehicles. It can be operated in buck, boost, or pass-through modes to optimize performance depending on the operating conditions. It has advantages of lower switch voltage stresses, reduced size of the magnetics and lower inductor conduction losses in comparison to single-switch buck-boost converters or other two-switch buck-boost converters. The operation of the converter in buck and boost modes is discussed in detail, followed by necessary mathematical modelling. To validate the effectiveness of proposed converter, simulation studies are carried-out with the help of MATLAB-Simulink. © 2023 IEEE.
