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 i_L1 > i_L2 or i_L1 < i_L2). 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.
