A New Multi-Output DC-DC Converter for Electric Vehicle Application

Abstract

Electronics on the go and EVs rely heavily on multiport converters. Various SIMO converter configurations have been reported in academic literature. Duty ratio and inductor charging are the parameters under which the majority of SIMO converters produce their outputs. The problem of cross-regulation is still present in SIMO converters. To circumvent these issues, this study recommends a SIMO design. The creation of the three separate output voltages is not constrained by any constraints on the duty cycle or inductor currents (iL1 > iL2 > iL3, or iL1 iL2 > iL3). Because the proposed topology sidesteps cross regulation problems, variations in the output current i03 (i02) (i01) do not impact the load voltage V01 (V02) (V03). Keeping the loads separate is an important aspect of regulation. In order to build the proposed system, MATLAB/Simulink is utilised to validate the simulation findings.
