Comparative Analysis of Multi-Port DC-DC Converters for Electric Vehicle Applications

Abstract

To provide an adequate energy infrastructure for electric vehicles. Multi-port converters offer superior design and execution capabilities than single-port converters, making them particularly advantageous for Electric Vehicles(EVs), The non isolated multi-port dc-dc converter(MPC) topologies are employed in regulating the power distribution across various modules, including photovoltaic (PV) systems, fuel cells (FC), batteries, energy storage systems (ESS), and loads. In this paper few topologies, Multiinput Multioutput (MIMO) boost converter, Dualinput Dualoutput (DIDO) converter, Dualinput hybrid step-up converter(DIHDC), and Four-port converter(FPC), are studied. This will give a thorough analysis of each topology and a detailed performance comparison to aid in the complete under-standing of the benefits and downsides. This study compares a number of components, modes of operation, direction of power flow capability, and design aspects. The simulations study are carried out in MATLAB/Simulink, and are validated with OPAL-RT. © 2024 IEEE.
