Integrated DC-DC Converter with Single Input and Dual Output for Electric Vehicles

Abstract

Portable electronics and electric vehicles (EVs) depend on multi-output converters. The literature has thoroughly investigated numerous single-input multi-output (SIMO) converters, especially addressing specific operating duty cycles and the present scenario during induct charging. The single-input dual-output (SIDO) converter is introduced in this document to circumvent these constraints. This unique converter has the capability to produce a number of output voltages, which may be absent if one examines the running duty cycles or the specific currents utilized to charge the inductor (whether iL1 > iL2 or iL1 < iL2). The proposed SIDO converter resolves challenges related to cross-regulation, confirming that the output voltage V01 (V02) remains stable despite oscillations in the load current i02 (i01). Another advantage is that it successfully solves common issues with anchoring ourselves between outputs. This arrangement was tested with a 300 W prototype circuit using modeling and experimental analysis.
