| Efficient and versatile charging solutions are essential for modern applications requiring portable energy systems. This paper presents a novel portable charger powered by an isolated split-core current clamp, enabling direct charging from power lines. The system utilizes inductive coupling to draw AC current from these lines, which is then regulated to a precise voltage for battery replenishment. The proposed design features an interleaved resonant topology with a semi-active rectifier, achieving high efficiency and adaptability to a wide range of input voltages. This architecture supports a variable DC bus voltage, enabling the resonant converter to operate optimally near its resonant frequency for maximum performance. To ensure a lightweight and efficient design, the converter eliminates traditional transformers, incorporating a capacitive element within the resonant network for galvanic isolation. A cascaded dual-control strategy in the interleaved structure ensures precise voltage regulation. Designed to be compatible with 1-6 cell Li-Ion batteries, the charger offers extensive versatility. Experimental results from a 2.5-200 W prototype, with an output voltage range of 4.2-25.2 V, demonstrate a peak efficiency of 94%, validating the effectiveness of the proposed charger for grid-connected applications. | ||
