Qudus Ayinde AROMOSE

• Developed full electrical & magnetic models of direct/inverse coupled inductors with small-signal linearization; validated using MATLAB/Simulink, PLECS, and FEMM.
• Designed and built EE core prototypes from market parts (E56/24/19 for 2-phase, E42/21/15 for 4-phase) with 20×0.5 mm Litz; realized target inverse coupling k ≈ −1/3 with bench inductances matching simulations.
• Architected a cascade-cyclic 4-phase interleaved boost converter integrating inverse coupling; implemented dual-loop PI control and a Sliding-Mode outer voltage loop + PI inner current loop; closed-loop tests on dSPACE DS1104.
• Achieved 92.5% input ripple reduction (21.4% → 1.6%), ≈ 52% core-volume reduction vs 2-phase, ≈ 97% efficiency, and dynamic response gains (overshoot 13% → 0.8%, settling 2 ms → 0.8 ms); ensured balanced phase currents.
• completed loss & thermal design with SiC MOSFETs + SiC Schottky diodes; verified safe junctions (≈ 91 °C MOSFET, ≈ 70 °C diode); experimentally validated on 2-phase Interleaved boost and buck converter test benches; delivered a transfer-ready methodology (modeling → sizing → FEMM → prototyping → control → thermal) for Fuel cell electric vehicle deployment.
