| Abstract: | This paper presents the design and experimental implementation of a bridgeless positive output Luo converter (BPOLC) optimized for power factor correction (PFC) in low-voltage electric vehicle (LVEV) charging applications over a wide AC input range of 75–260 V. By eliminating the conventional diode bridge, the proposed topology significantly reduces conduction losses, improves conversion efficiency, and ensures a positive output voltage with a minimum component count, making it well suited for compact and high-performance charger architectures. The converter operates in discontinuous inductor conduction mode (DICM) to inherently support power factor correction; however, maintaining near-unity power factor under varying input and load conditions necessitates a robust control strategy. To address the limitations of conventional PI controllers, an Interval Type-2 fuzzy logic controller is employed, offering enhanced adaptability and superior dynamic performance across all operating conditions. Experimental results obtained from a compact hardware prototype with twelve active components validate the effectiveness of the proposed approach, achieving a near-unity power factor of 0.9967 at rated input voltage, total harmonic distortion below 2% in compliance with IEC 61000–3-2 standards, reduced input current ripple, stable output voltage regulation, and excellent transient response during input voltage variations. The integration of the BPOLC topology with Type-2 fuzzy control thus provides an efficient, reliable, and standards-compliant solution for next-generation LVEV charging systems, supporting grid-friendly and sustainable transportation infrastructure.
