A novel fuzzy logic control for a zero current switching-based buck converter to mitigate conducted electromagnetic interference

<span lang="EN-US">This research provides a new control technique for mitigating conducted electromagnetic interference (EMI) in buck converter designed solar applications. Indeed, hard-switching direct current to (DC-DC) converters, commonly used industrial applications, pose significant risk the surrounding environment regarding compatibility (EMC). Usually, fast-switching phase induces abrupt changes and voltage, which adds substantial both radiated modes excessive auditory noise. An architecture based on duality of soft-switching topology fuzzy logic technology is developed address these issues. On one hand, resonant circuit topologies are induce switches achieve soft switching conditions, subsequently lessen effects EMI. other adoption interesting since it can reduce electrical stresses during switching. Furthermore, simulation results show that zero (ZCS) closed-loop converters outperform typical open-loop with proportional integral (PI) terms EMC requirements.</span>
