Innovative Inductor Topologies for Enhanced Efficiency and Performance

In this paper, multiple innovative inductor topologies are presented for enhanced parameters including magnetic flux density, energy density, and current densities. The designs results are validated through COMSOL simulator and measurements. First, a straight wire inductor (length 900mm and diameter 0.67mm) is simulated for magnetic energy density ranging from 4 to 14 (J/ ). The inductor configuration is subsequently transformed into a range of nested topological variations. The innovative design predicts that the inductance is increased from 114.33H to 129.68H by varying the shape of inductor into circularly bent. Moreover, the magnetic flux is increased from 2 to 15 mT. The simulation and measurement outcomes closely align with the proposed inductor design. These findings indicate substantial potential for the utilization of the suggested configurations in wireless power transfer and resonant circuits. The incorporation of nested arrangements enhances magnetic coupling, leading to improved energy transfer and reduced losses, thereby enhancing overall efficiency.
